To make it easier to know which wire from the 97 goes to which wire on the 92, let us start making a table so it is easier for others who can't read wiring diagrams to follow.

Since I am not taking out the old 92 plugs , I will just solder the wires from the new cluster to the corresponding wire on the old cluster so I can use either gauge clusters. Though you will do less soldering and repinning if you just replace the old 92 plugs with the 97 plugs .

First lets take a picture of each plug we will use so it will be easier to follow . As I have shown and said on the "2jzgte Wiring Harness Made Easy" thread, numbering of pins usually start on the left of the plug with the plug lock on top. I have also shown on that thread how to pry a pin out so check it out if you don't know how to . I don't feel like repeating that info here. But let me give you the link again of that thread -> https://www.clublexus.com/forums/per...made-easy.html

NOTE : There are other pins / wires from the 1997 plugs / pigtails that need to be wired / connected

1) Pin D1

3) Pin D19 should be wired to Pin 5 of the TEMP/ODO switch which is empty right now .. those pins are for the TEMP display.
4) Pin D21

I did cut the cluster wiring , 12" from the pigtails



Today .. took out the dashboard of the 1992 SC300 so I can take out the dash harness and start the grafting






1992 SC300 dash harness has some minor differences from that of the 1994 SC400 dash harness so I will use mine from the 1992 SC300 to graft the 1997 pigtails.

This is where I am grafting the 97 pigtails. In that area inside the dashboard, there is enough room at the back to hold the bulge caused by the grafting. Remember, I am not taking out the 1992 plugs. I want to be able to use either of the two clusters..... pre 97 or 97 gauge cluster. It is a lot easier to cut and remove the pre 97 plugs and just replace. But the beauty of just grafting the 97 plugs is you can use either of the two.



Plug A of the 1997 gauge cluster grafted



Plug A & B of the 1997 gauge cluster done



Plug A , B & C of the 1997 gauge cluster grafted



All 4 1997 gauge cluster pigtails grafted



The sphagetti junction... need to properly wrap this thing. It would have been cleaner if 1992 plugs were totally taken out but I still want to have the capability of using a 1992 gauge cluster so I kept them. Just need to properly wrap that thing,.



The 97+ trip switch plus the plug





The 92 trip switch do not have a wire on slot 5 so it has to be added and connected to D19

Picture on top is from the 97 and picture at the bottom is from 92 .. slot 5 is empty as stated. That slot is is for the TEMP Display

Initial Testing shows it works. Tested two different 97 clusters

Gerrb,

I wish I had this information like three years ago. I think you are the only one that has successfully completed this. You again, have surpassed as being the "LEXUS SC GOD".....

Looking forward to this write-up Gerry.....Does the cluster funciton 100% i.e do you get the outside temp gauge..etc.

My car is living proof that it is possible to get a up and running Aristo 2JZGTE swap following his guide.....

Thanks guys... I have a lot of people PMed me saying they got their 2jzgte swap wiring harness done using that guide you used Ryan.. Some had a couple of problems here and there but after explaining things to them.. got things working.

I have verified every pins / wires on the Gauge Cluster Conversion table on post #2717 . Except for one or two pins... every wire from the 97 has been matched on the 92 so I don't see any reason why a 97 would not work on a 92.

Honestly , I have yet to do the actual cutting and grafting of wires and testing on my 92 but as mentioned , the table above clearly shows me everything will work due to the matchup.

I maybe wrong but after all the diagram analysis... I have no reason to doubt it will work . BTW, Ryan , for the temp , not sure. I guess we will find out..

Now I need to remove my Red Mamba Two (1992 SC300) dashboard to take out the cluster harness and graft the 97 pig tails. What I currently have whose picture I took was from a 1994 SC400. Surely very similar but I would like to verify .

Here I am again cluttering your thread.

So....I am hoping you will pick up another 1 of 120 1997 5-speed. You can stay at my house if you decided to come down

Dennis - thanks for the offer buddy . I think I will pass and let another forum member have it. I would like to keep the 3 1992 SCs I have now since all my SCs are gonna be built 2jzgte. Having 1992s, in 2 years time I won't have to get them emissioned / inspected for which highly built 2jzgte wont pass since there are no cat converters. If you only know how it is done now just to get them registered... . Another reason why I have no interest on working on that 1997 5 speed I have at the moment even if I have the complete drive train and top notch bolt on parts for it now. I am even tempted to sell the bare shell if not for its rarity and just keep the 3 1992s just not to worry anymore about emissions and inspections or maybe bring it to stock for now since I have everything from another 1997 .

Well guys... check Phoenix AZ and San Rafael CA.. there are two 1997 SC300 5 speed for $6400 .. both from dealerships. I hope forum members get to own them. They seem to be very clean cars.

Also if anyone here in GA , wants a black 1996 SC300 auto tranny shell let me know cause a friend told me he is selling his shell for $1000...no drivetrain and interior is not in great shape. He is scrapping his SC project and instead was installing his 2jzgte swap into a 240sx.

irondonkey

hmmm i'm gonna ask my friend about the shell.

irondonkey

i'm getting a hugeeeee itch to mod the SC... and throw in a stock 1jz..

i def can't go 2jz due to the costs involved, and what i'd like to do it.

either way, i'll be running it stock for a while. im swaying towards the 1j due to the costs of being able to do it so much cheaper....

gerrb

What ever JZ swap you choose should depend on your final goal for the car. What will its use be so you get to decide your power goal and ultimately the setup you need to work on. I know 1JZ is cheaper but at the end of the day, you will be throwing money away if you buy something now just to change things down the line, you might as well wait and save for the right setup .

Like Rey just told me last night, he has a friend who wanted to change his 400rwhp 1jz / R154 setup into V160 / 2jzgte 800rwhp setup. I know hind sight is 20/20 . We all change our mind , always...doing it right the first time saves tons of money though.

so when will the black beast be ready? or is it the Red mamba? lol

irondonkey

the only reason im looking at it is because my stock SC is getting terrible MPG.

i'm maybe at 110-120 miles, at a half tank.
