ECU jzx100 pins

[splatt]

this is how different, I'll put up a complete diagram in a couple of days, these are the wires and traces for C85 16 pin,
(There have been no mods to plug,)
pin1 blue/pink
p2 pink/black
p3 grey/red
p4 white/blue
second row, only 2 pins used
p5 green
p9 brown
third row
p10 light green
p11 light green/red
p12 blue
p13 yellow
bottom row
p 14 vacant
p15 green/red
p16 yellow/green
p17, p18 vacant

only 12 pins used on C85
ECU part number 89661 22800
1JZ- GT AT(automatic transmission)
definately from JZX100, I bought the half cut with ID plate.Had it running in cut, just hooked up a battery,tank and pump, fired and ran on first touch of key/starter. (Even the air con worked)

Quick tip for you Splatt.
Toyota changed the wiring colours more often than you change your underwear.

Obivously the main colours have remained the same, (power, earths etc), but most of the time the sensor wire colours will change, sometimes up to 3 times in the one year.

Usually if the plugs are the same, and the pinouts are the same (location, number of), then the wiring is the same.


EDIT, just looked at the difference between your pinout and his.
I'd open the ecu up and look.

I sort of wish I'd kept my underwear on longer

here's some of the JZX100 electrical stuff I collected from the net and then started to put together a doc with the pinouts a while ago:

Thanks, this one looks like it's the same one that Graham, and Giant Tomato posted, I think if you look at their posts it will fill in the gaps, the Chaser whole car one is out there on the net , semi- translated.
I have found a few manufacture date codes on some of the plastic bits, most made November/December 1996, so I think I am safe to assume that it's a 97 model,
Following Giant Tomatos advice I have spent 2days with a multi-meter (one more to go) tracing wires from engine bay to ecu,not only are the colours radically different but the pins used areTOTALLY different! There are FIVE other plugs on the engine loom as well as the 4 ECU plugs
I should have most of them logged this week, will post list as soon as I get them all down. -twitch,twitch!

Hey All,
if you want help on wiring up a JZX100 loom, I have done this, and I had to start from scratch.

PM if you want some info.

Cheers Nilezy

Thanks, all done . finished yesterday, Jim(Sideshow) hadn't done one before, He worked it all out , Top gear electric hookup was only big problem , he's now the expert on that as well.

Does anybody know if the ECU is the same for the 1JZGTE VVTi JZX100 and the VVTi JZZ30 Soarer?

Im looking at getting a Power FC for my soarer, only thing is it came from a JZX100 and i believe these are a straight swap into the loom. Anyone know if it will swap in ?


Thanks,

Dylo

part number on 1997 1JZ Vvt Auto Chaser is in photo,don't know part number for soarer,
As you can see from thread there were at least 2 different ECUs used in JZX100 s(both turbo and auto, and there is a different one again for manual trans. ECU in auto controls transmission as well,-this is a completely different trans to non Vvt models like JZX90 TT)
confused??some wire colours showing in pic, it gets worse!
good luck.

Go back to post 19 the file there has one, i am currently working though my JZX100 1/2 cut wiring, its a time consuming job, doing it and documenting it all.

[aimi0803]

hi splatt...can you tell me where the yellow and light green/red wire from speedometer are gone?..my speedometer not function, 1jz-gt 2.5 automatic 1996

Pls help me

first pic, the ECU with the plug ins from the engine, these I should not have a problem with, it's the other two out plugs, I got it in a half cut(auto) so most of the pins will be for throttle control,ABS,don't need, etc, some will be for auto and sensors (needed)2nd pic is of two plug ins that I need the pin code for.

[splatt]

I'm not using the JZX100 speedo,Wire from the VDO I have will run to plug in ECU, Sorry can't help, but the ECU is under dash on top of glovebox, without removing dash, can't even see it.(and if I did there is a chance it would be using different wire codes, why,why, why does Toyota use several, completel;y different coded looms???)

I am as new here as new gets and admittedly here mostly for this wiring help. Hi to everyone on here from the old US of A.




I am swapping a 1jz vvti M/T from a jzx100 into my R32 Gtst and have found all this info in this (ollldddd) thread very helpful. I figured rather than start a wiring thread as my first post, I would just revive the one that helped me so much so far.


I have two basic questions.

1. What is the plug that comes out of the engine loom and has 15-20 Black/white stripe thick wires in it for? power to sensors? I DO NOT thiink it is ground as grounds have been brown or white/black stripe so far.


2. Since I am not using traction control/do not need fuel pump turn on through ecu/ do not need gauges to work through the ecu harness/etc. Can I just power up the basic stuff that gets power on the 28 pin and 16 pin connector, ground what needs grounding, and fire this thing up????


Thanks for all your help in advance!

Nilezy?

Anyone?
