I have a '03 2500HD 4x4 I swapped a 2004.5 LLY into. Working on all the wiring as the frame/cab I used had no wiring in the engine bay area,(no fenders/etc..).
I have finally gotten the main fuse panel re-wired/connected. I have the engine harness settled - looking for what a lot of the smaller connectors by themselves mate to on the drivers side between the engine and fender and from the radiator to the firewall.
Also - a close-up of the LLY ECM mount? I have the LB7 PCM mount and that is obviously a little bigger. Trying to get an idea of what the smaller mount would look like.
Any pictures or pointing in the right direction is much appreciated!
