Wiring question. X90 Auto harness into A70 Na 5spd

[mattsplat72]

I cannot find the eb1 or the eb2 plugs ....I know were they are "supposed to be" but the are not there.

I have none of this? nothing on car side and nothing on harness side to indicate that it was cut?

I am also missing the Yellow plug.

I have a 14pin grey , a 22 pin grey, on a smaller bundle
I then have the two ecu plugs, a white one that is capped and a white twenty pin. I don't know what one is which.

I am trying to figure it out by using a soarer write up. This is for a chaser harness into a 92 na

Matt I take it your harness is cut? I truly to make this easier on yourself would get a new harness. It may take a long time to find every wire. those stupid soarer and chaser harnesses have a lot of the same damn colors too !

 

[mattsplat72]

Nope, I took the trac control and AC shit out of the harness,

I re-loomed the entire harness and there were no wires cut, no stubs from, there is literally nothing to indicate that there is anything missing. I wonder if the plug for the TRAC system is the yellow one that I am missing...

What about the EB1 and EB2 plugs I do not have either the female or the male plugs. I do not know where the would be.

I need this info as well, currently doing a sc300 w/ jzx90 chaser 1jzgte.
I think the fat plugs are for powering the inj, coil, ecu.
The skinny 2 row plugs are for the dash lights, and tach, spd, etc.

which is which?

gravedigger. lol

well as far as the eb1 and eb2 plugs they dont exist. I went to a pull a part and got a plug ( both sides) and then looked at the TEWD to see what wires the connected to on the car side . This gave me a reference point on the harness side. Car algebra Car side + X = Harness. Some of the connections were the BATT,B1,B+1, MREL.

I got rid of those plugs by getting rid of the DIAG block. I only saves te1 and e1 for code checking.
Your best bet is to label every plug on the 1j, Then take it off put it on a board and start tracing wires that way you know what goes to what and what is useless. It is easier that way. The x90 and z30 close but not exact. 92teals right up is a good start but not complete.

Little more info in my build thread http://www.supramania.com/forums/showthread.php?110860-My-92-3e5-Supra/page2
