Ok I searched and found a couple of Links to some Factory service manuals but not exactly what Im looking for, does anyone have a good link, or can post a copy to a 1990 toyota 2wd ECM pin /wireschematic?

I think My ECM has a 20/16 pin setup, I need to know what color code wires go where,

(If anyone needs to know, Im putting a 4cyl 22re from an 87, into my 1990 4runner that had, a V6,..Pulled the V6 Wiring, scored a complete harness from an 90 22re, so I just trying to match everything up) All ready I switched the sensors,/fuel injectors,/TPS, because the plugs were physically different) Seems I have more than a handfull of plugs left over,...?Anyway, any help is grateful.

Tom-

 

Let me get this straight......You're trying to use an ECU from a V6 to run a 22re EFI system? I don't think it's going to work, mate.

 

No, Im putting an 87 22re motor in a 1990 4runner that HAD, a V6, No longer, HAD a V6 wiring harness,No longer, didnt have a 4cyl wiring harness for my 87 so I got a 4cyl one and ECM off a 91 2wd pickup, I going to make it work

 

Okay....I understood you swapped motors and harnesses, but you're first post wasn't real clear on the ECU part. So, had to ask.

I don't have the schematic or know of anyone that has one for that vehicle on this forum. But, I've had luck calling my local dealership and getting a copy of different pages from their shop manuals. Maybe you could try that.
