I need help with the wiring to go from a 4l60 to a 4l80 since i cant find an adapter for my year model truck any info on this will help thanks

 

Find a 2500 or 3500 same year in boneyard??? Probably be easiest route!!!

 

Ya thats true but what would you say all i need to make it work right beside reprogramming the pcm and ive found a bunch of forms on repinning but they are for 96 and up and from what ive read theres a difference because the 95 is a obd1 and 96 and up is obd2 and if i could find the pinout for it i would go that way but like ypu said finding one out of a 2500 would probably be easier if i can find one

 

Pinouts and diagrans are available but the harneses being 20 years old rather see if i couldnt find a donor vehicle for the harness....

 

Ya would you take the whole harness or just take the plug and wire it to the old harness

 

If i could id probably take whole harness..... Especially if i could find one with same engine..... Not that harbess werent much different, also grab the ecm or at least the prom out of it

 

Alright thanks for the help i really appreciate it
