Thanks for the pics Jamal.
Other than the PCM, what changes did you have to make?...I.e. wiring harness, fuel pump, mounts, exhaust, fuel lines?
Did you use the original trans. or a 4T65E-HD?

 

I changed the bcm all the wire harneses from the dash to the body , abs computer ,gas and brake paddle with sensors. The fuel pump stayed the same and fuel lines were cut and reinstalled with clamps n reinforced tubing. My ls4 came with the hd trans already mounted. I also changed the steering colum, dash with hvac system. The last part about the swap i didnt do yet is get everything programed by the dealer so i can crank from the key. The exhaust bolted into the stock 01 but will be changed soon

 

Impressive!
How did the wire connectors match up. Have to do a lot of splicing?
I assume your limiting the miles you drive until you get the PCM/TCM programmed considering the trans. differences?

 

I replaced all the wiring with 06 wires the only connector that was the same the the fuel tank connection
