I have posted a while back about this before, but did not get a definitive answer. I am almost finished, but need a little clarification before proceeding.

I have a 98' 4runner ltd. Bought it with the RR diff lock all set up. Long story, but I ended up having to buy another ECU and switch for the locker. Problem is, the switch and ECU are from a tacoma (has only one grey wire as opposed to a red/blue wire - for a 4runner). I need to match the wires from my new, Tacoma ECU, with the wires from my 4runner's locker's harness.

If ANYBODY, with an ECU for a 4runner can simply look at the wires connecting to their ecu, and read off, in order what color they are, I can simply look at the numbers and match the wires. I would greatly appreciate this.

Thanks in advance. Hope someone can give some help!

 

if u look on line at the repair manuals and look at the wiring section u can find the answer u are looking for,
