wiring ISSUES!!!!!

So I just swapped an 87 b2600 body and harness onto an 89 b2200 frame with motor. The harnesses are not the same like I had hoped. I need to know which wires are for the oil temp and water temp on the side of my b2200. Im trying to find the wires out of the b2600 harness but so far no luck. Anyone with an 87 B2600 wanna look for me??? Also since I got rid of my computer because of my weber, do I still need the wires that run up on top of the transmission still?

Dont believe they are compatible. The 2600's are sooo different. Your best bet would be to sell the 2600 harness and find a 2200 one. Unless you are really crafty with wire....then it is time to break out the good ol wiring diagrams.

That may help....

thanks jeff, but that website doesnt have any info on the 2600 harness! ugh.......I got the truck to run, all the lights work inside and out. The only thing I dont have so far is my water temp and fuel guage. Im swapping the pumps out of the tanks and swapping tail light harnesses too since the tail to cab plugs are different. Is the sender at the bottom of the radiator on my 89 with the 2 round plugs a water temp sender?

Sorry my bad... You may try a search on this site...don't know...

Hey Josh if you are out there do you know??????
