Ok here is my problem i have a 89 toyota pickup with a 22re in it, well i bought a motor for it and it came with the computer and wiring harness so i could just set it in, plug in the harness and go. I already had a wiring harness but since the motor i bought had the harness already ran through out the motor i figured i would just unplug my old harness and computer and put the new computer in and plug this new harness into the dash. Well i pulled my other harness and computer and noticed the computers were different well thats ok because i have the harness that went with that computer but the 2 plugs that plug into the dash were different which made no sense. So we were thinking about that for a while and the 22re i bought is out of a 91 but i dont know why the plugs would be different. If you have heard of or dealt with this i could really use your guy's help. Thanks.
