Nothing much here except overlay wires / plugs to be merged

Most of my extra wires are near the auto transmission plugs . I have around 14 on that area... plain and simple ...sucker for extra wires

Extra wires and the 80 pin ECU connector. All these wires have already been extended.

At this point this is how our SC300 harness looks like after the process of elimination. This is for the 2jzgte swap with auto transmission. The SC300 harness for manual transmission will have a lot fewer wires left.

These are wires I just cut (from Diagnostic Port , Auto Transmission ) which I will use to connect to our Aristo 2jzgte harness. As I mentioned , for the manual transmission swap harness .. more wires have been removed and most of these you won't even have anymore. There is a plug with a wire rolled with this which I really don't know what it is for at least for now. But when I go through Part IV of the harness build I am sure I will find out since I will comb through the wiring diagrams looking for what else should be connected to the body plugs.

Just to prove what I said in the previous post that the Manual Transmission harness will have a lot fewer wires , this is how the two IK1 and 40 pin plugs look like

IK1 for the auto transmission has more pins / wires

From here , for those who already know what to do , they just overlay the SC300 harness on the 2jzgte harness or put them side by side and start connecting wires from the 2jzgte harness to the different pins on the 40 pin ECU connector and all the other plugs. They also start moving around or removing those wires / pins not needed on those plugs. That is easy for those who already know what to do.

Just like pictured .... our Aristo 2jzgte harness with auto transmission plugs and the 1992 SC300 harness that will maintain the auto transmission plugs.

You already know where the fuse plugs , alternator , horn , power steering plugs should be in relation to your engine bay. So they need to be in their respective areas of the harness.

As I have said this is where all the merging of wires take place. Make sure that when you merge wires, those body plugs will be near the 80 pin ECU connector so watch out how long the wires of those body plugs you are merging should be.

The above process may still be confusing for those who never did it before . Take note what I said in the beginning of this harness build , some of those pins / wires that are currently on the different plugs like the SC300 40 pin ECU connector may not be used the same way as that on a 40 pin ECU connector for the 2jzgte. Remember ? Not because they are both 40 pin Connectors , all their pinning are exactly the same or used exactly the same way so you need to verify all the pins that are on those plugs.

So is it better to de-pin those plugs now and start connecting wires based on our CHART ? This depend on how well you know by now what is needed and not needed on a 2jzgte and from the 2jzge (SC300) connectors. So for those who have never done it before , probably so .... starting from a clean slate of plug will be less confusing for them and just add the pins one by one .

This you should have deduced from your CHART. Which wires from the Big Gray Aristo Plug goes to which pin of which plug. It is just another way of presenting what is already on your 2jzgte CHART . Let me explain this next chart a bit which I will call "Body Plug Chart" ..when I say AF1 , it means Aristo , Plug F , Pin 1. Let's take Pin 2 of IK1 . It simply means Pin 2 of the IK1 Connector (Orange with 23 pins) should be connected to the wire which we took out of the Aristo Plug E pin 7 (AE7) . If you have labeled those wires properly before , you should easily know which one it is. This same information , if you look at your CHART is already actually given but written differently under ARISTO CONNECTOR , PLUG E .... check it out , it's the SC3 data on parenthesis . So why am I presenting it this way ? Just for us to have a quick glance what is all going into the different pins of each body plug we are merging into the Aristo 2jzgte harness. We did the same thing on every plug of that 2jzgte harness .. remember your CHART ?

BODY PLUG CHART

IK1

2 <--> AE7
3 <--> AF10
4 <--> AF4
7 <--> Pin 1 of Noise Filter
8 <--> AF12 <--> Pin 1 of 4 Pin Igniter Connector

7 <--> AE13
9 <--> AE9
10<--> AE10
19<--> AE7
20<--> AF4
31<--> AE3


Let me remind you though , not because you have connected all those wires from our Aristo 2jzgte harness to those body plugs , it is a done deal .. NO it is not , there are other pins on those body plugs that needs to have wires / pins . Those we will cover on PART IV OTHERS. I will post the diagrams also just for you to know where are they coming from (e.g. A pin from one body plug maybe connected to another pin of another body plug or let's say you currently have a car with auto transmission and you are converting to a manual transmission, there are wires / pins you need to work on. That car won't start without modifying / repinning some plugs (hint : a car with an auto transmission has a PARK safety switch which you need to bypass ).

Please take note :

1) From now on when I say Body Plugs , I am referring to all the plugs we extracted from the SC300 harness meaning the 40 pin ECU connector and other plugs like fuse box plugs are included.

2) Informations that are presented on the MERGING PROCESS is all for the SC300 car since I am dealing with body plugs for the SC300. If you have the SC400 or MKIV NA , use the pertinent informations on parenthesis from our 2jzgte CHART.

3) Before you start doing the merging process, You make sure you have enough wires and pins for the different body plugs. Why pins ? It is because a 2jzgte setup will use more pins. Like the 40 pin ECU Connector for a 2jzgte will have more pins / wires than the 40 pin ECU Connector you currently have on your SC300. Or if you have an SC300 with manual transmission and want to swap a 2jzgte with auto transmission , then you know you definitely need more pins / wires which your current manual transmission body plugs do not have.

So where do you get those wires and pins for those body plugs ? Somewhere , I remember saying (in one of the Q&A on the other thread) , if you can get hold of another old harness (from a 1uzfe, 1jzgte , 2jzge or any toyota car with the same plugs) you can use for extensions then you will also have extra pins for the same body plugs.

I will post pictures here (post 81) of the SC300 harness body plugs wires soldered / merged with the Aristo 2jzgte harness once am back in town. I haven't actually done that yet on the two harnesss as of today . But would like to continue posting on this thread on my free time (got lots of it sitting on the plane & waiting at the airports ) info in which I don't need the actual harness .

Part IV : OTHERS

On this part of the 2jzgte harness build , we will go through all the SC300 / SC400 / MKIV wiring diagrams. We will try to find those pins and wirings that go to the different body plugs / connectors. Though there are not a lot of differences between the year / model of cars , still there are differences on their wirings. If you can go through your year / model wiring diagrams , that will be the best.

I know some of you may not have the complete wiring diagrams for the SC300 or SC400 or MKIV NA. I will post them here maybe 5 to 8 pages per post so you have all the wiring info you need for your car while we look for those wires that go through the Body Plugs and ECU Connectors. Just like I said at the start , we will try to put all the info you need in one thread so you will find it easier to build a 2jzgte wiring harness and have the tools to verify what you are doing. If you couldn't read the diagrams because of the picture size , click on the picture , and magnify them there by clicking the + sign to enlarge the picture .

If on a diagram , you see red ellipsis, that means we haven't covered that and you will have to add that pin / wire on your body plug. There maybe some pins / wire that has no ellipsis but I still added on the list just because during the time I was working on the JPEGs I forgot to encircle them but noticed them during the write-up... sorry about that. Going through the diagrams, you should be able to complete the list of wires that go to the body plugs.

Remember , as I kept on mentioning ,I am trying to show you the process of how to do it. This write-up is not for you just to copy whatever I have written. I am pretty sure there will still be typo errors or might have missed something even if I have been proof reading what I wrote. Knowing the process, you will be able to verify for yourself what have been written here . Diagrams I am posting here are from 1992-1994 SC300/SC400 . There are some differences with the later years so make sure you use the diagrams for your particular car year model.

Going through each diagram , we will look for each body plug with their associated pins and wires.

[SIZE=&quot;3&quot;]For SC300[/SIZE]

Alternator Connector
Pin 1 of Alternator Connector goes to Pin 2 of the EB2 Connector
Pin 2 of Alternator Connector goes to Pin 5 of the IJ1 Connector
Pin 3 of Alternator Connector goes to Pin 13 of the IJ2 Connector

EB2
Pin 2 of EB2 goes to Pin 1 of the Alternator Connector

IJ1
Pin 5 of IJ1 goes to Pin 2 of the Alternator Connector

IJ2
Pin 13 of IJ2 goes to Pin 3 of the Alternator Connector


[SIZE=&quot;3&quot;]For SC300 & SC400[/SIZE]

Starter Connector
Pin 1 of the Starter Connector goes to Pin 1 of the EB2 Connector

EB2
Pin 1 of EB2 goes to Pin 1 of the Starter Connector

EB1
Pin 3 of EB1 goes to Pin 23 of IK2 & to Pin 5 of the Park / Neutral Switch (& to Pin 8 of IJ2 (Manual Transmission Cars from Factory))

IK2
Pin 23 of IK2 goes to Pin 3 of EB1 & to Pin 5 of the Park / Neutral Switch

IJ1
Pin 6 of IJ1 goes to Pin 6 of Park / Neutral Switch

IJ2
Pin 8 of IJ2 goes to Pin 3 of EB1 (for manual transmission cars only)

NOTE :

a) For those who originally have an auto transmission car and are converting to a manual transmission, , you will need to jump the pin 2 & 3 of the Park / Neutral switch which is like connecting Pin 23 of IK2 to Pin 6 of IJ1 . If you don't do that , your car is not going to start because of that Park / Neutral Safety switch that is not activated due to the fact that you don't anymore have an auto transmission.

b) On the diagram above, you see connections point EA1-1, EA1-2, EA1-3, EA2-1 for the SC400 alternator. Those are mere hard wires. There is no actual plug. So for the SC400 , you need to connect your alternator plug to those wires. The plug and wiring for their alternator is not incorporated on the engine harness while that of the SC300 is.

c) From the starter you also see the wire goes to connector ED2-2 before it goes to EB2-1 for the SC400. Since you are going 2jzgte , you won't have that ED2-2 connector anymore so the starter wire goes directly to Pin 1 of fuse box plug EB2 just like that of the SC300.

d) There are other connectors for the SC400 like Ee1-1 , Ee1-2 . Since you are doing away with the 1uzfe and installing a 2jzgte , you won't have those anymore.

e) The beauty of going through these diagrams at this point is if you miss something along the process, there is a possibility that you will catch it. I was scanning on the body plug pins associated with the diagnostic port, then I realized there is a pressure switch for an SC300 which the SC400 did not have on the diagram . The wire goes to Pin 35 of the 40 pin ECU connector. During the process of elimination I actually noticed the wire of that plug going to Pin 35 of the 40 pin ECU and I just put it aside for now till I figure out what it is. The diagram helped me figure out what it was for.

f) When you see an arrow on a diagram and numbers in parenthesis , the numbers in parenthesis tells you the page and section where that diagram goes or comes from .

g) Updating your Body Plugs Chart helps you see what is already filled up on your body plugs

Since you are installing an A340e from a 2jzgte, you cannot use the A/T switch pin numbering on the diagram above. If you go back to the post where we worked on the A/T transmission part of the harness, the A/T switch numbering is different.

Since you are installing an A340e from a 2jzgte, you cannot use the A/T switch pin numbering on the diagram above. If you go back to the post where we worked on the A/T transmission part of the harness, the A/T switch numbering is different.

I just want to thank you for such a huge contribution to the forums. Something this detailed is really hard to come by. Everyone who will be following this when they do their swap will save lots of headache and money.

GOT IT !!! lmaol.

When I was doing the process of elimination on the SC300 harness , I accidentally cut the wires of the 3 pin Connector for the Speed Sensor without checking where the hell the wire goes. If you check back our chart , I just put there GOES TO BODY PLUG .. haha.. cause I didn't know where the wire goes but I knew , once I go through the diagrams one by one searching for what goes to body plugs I will find that sucker and this is it pictured above ! Again the beauty of going through Part IV .. scanning through all those diagrams , you will eventually find what you are missing.

For SC300 & SC400


IK1
Pin 6 of IK1 goes to Pin 2 of the Speed Sensor 1
Pin 7 of IK1 goes to Pin 3 of the Speed Sensor 1
Pin 20 of IK1 goes to Pin 1 of Oil Pressure Switch

IK2
Pin 10 of IK2 goes to Pin 1 of Oil Level / Oil Temp

IJ1
Pin 10 of IJ1 goes to Pin 1 of the Speed Sensor 1
