Hi, i am looking for a wiring diagram for the 1jzgte vvti i just got. if i look up the ECU number it tells me the JZX100 from a chaser. it is mated to a r154 (5speed tranny) I am doing this swap into an 92 sc300

if someone can help me with diagram that would be appreciated

i need the pinout for the 4 connectors i just got the 2 harness connectors the body connectors were missing here are the colors on my 2 connectors.
Also if someone has the 92 sc300 5speed body connector pinout that would be helpfull

the ecu # is 89661-22790 everything after the  sign is information I collected online and not sure if it would apply to my ecu. wire my throttle, wires color is what i got on my connectors.

2-(no wire)
3-(no wire)
4-(no wire)
5-BLK/W NE+ check connector may be not necessary depending on how FP is wired??
6-G NE-  connector H pin 10??
7-Y/BLK VTA1-TPS
8-G/BLK  VG  connector H pin 4?
9- (no wire)  COR power (splice for all blk/r wires, power for ISCV, all VSVs and B on diagram connector??)
10-R VVT
11-(no wire)
12-Y/G VTA2-Track butterfly  splice off of this wire for connector J pin 13??
13-LIGHT PINK  OX
14-G/R VT02-Trac ecu

I found some body plug pinouts but then I realized want to double check the function on the connectors so what you really want is this https://www.clublexus.com/forums/per...ion-sc300.html

i think you made a mistake on the thread. there is no body plug pinout or information on body plug pinout. This is to install the SAFC. and it is talking about wires on the ecu connector.

Updated.. Like i was questionning it i am pretty sure now that the Throttle control ECU is in fact the Track ECU so i am pretty sure that the engine is not DBW.

so the thing i need now is the pinout i have for the ECU 2 body connectors is right. and i need to know the sc300 body connectors pinout as well.

thanks

You trace the body plugs from the ECU plugs or vice versa from the engine bay plugs.

Exactly. You are pretty much stuck tracing stuff backwards from the engine bay plugs back to the ecu connectors and body plugs to figure out what is what. Even with cheat sheets and pinouts, I had to do a lot of manual tracing when I converted my Aristo harness.

I have everything u need pm ur e-mail

yes i know i would have to wire trace backwards but it would take a long time so i figured i would ask if someone have done it already.

T70 supra, i sent you my e-mail. thanks for your help.

Cool deal. If you get pinouts, post them up. Then maybe we can be more help when this question comes up again

Hey Adam, where did you get your motorset? I'm looking to place my order this week but ebay doesn't seem to have anything decent available.

i live in canada and i took it in a place close to toronto pm me if you are still interrested. i dont know if they still have other one 5 speed maybe they ordered another one in??

use a jzz30/jzx90 pinout for the two plugs that didn't come with your swap. It should work.

also, there should be a blue plug where like 11 wires or something come together, black with white stripe, that's all the crap that needs power to it.

thanks buddy, i already saw this thread though, all the diagrams i got are all chinese... and i do not speak chinese or japanese. I found a factory sc300 manual 4000+ pages. working on tracing all body wires i will need to hook up to ECU and other important parts. and to trace the rest will be multimeter (for 1jz vvti harness) and then do the pin out.

If you have the pinouts to your stock ecu, just match corresponding pins to this:
http://i187.photobucket.com/albums/x...e/jzz309gp.jpg

The plugs you were missing that include +b, w, mrel, etc. Will be the same as these. Disregard the engine function pins as they are not the same.

Like I said before about the blue plug with the 11 blk/wht wires, those are your power to sensors. Coil (x3), igniter, maf, iacv, ignition dampener, o2, and vsv ( I believe also x3). Wire those to the same places that your stock ones are wired to, fill in the plugs missing with the pinout above and you should be in the game.
