Hey people ,I'm new to the forum, I'm having a tough time with the swap I'm doing. Putting an 08 5.3, trans ,and t-case in my 04 reg cab short box . I have both ecu,and harness's and both fuse box's. I've been trying to find proper wiring diagrams and pin locations for both 04 and 08 with not much luck ,any help would be great

 

There is no official documentation on a swap like that.

It's not an easy task because the communication protocol systems are different.

 

Thanks for the reply ,I may have to see if some has what I need and is willing to trade this was the only motor available to me at the that was worth spending money on , thanks again
