The truck side harness end for both LB7 and LLY are physically the same, they'll plug in under the main fuse box in the engine compartment on top of the inner fender (driver side).

LB7 to LLY
The truck side LLY harness from the 4.5 doesn't need to be modified by anyone, just plug it in (03-04 are plug n play). Along with the ecm/ficm from the lly.

Swapping Dmax into vehicles - Need wiring Info/Help
The way communication happens between the engine and the rest of the vehicle changed in 03 for the duramax........... 01-02 are the same, 03 and up and different.

Swapping Dmax into vehicles - Need wiring Info/Help
I'm sure someone else will chime that may have better answers then me, but more then likely you will need an 03/04 truck side AND engine harness. The 03/04 harness's should communicate with your existing 07 setup and plug right in. You may have to modify your fuel scaling in the ecm. Also you'll...- rfletes79
