Ok I just bought a 04 sierra 2500hd slt crew cab 4x4 loaded truck with 36k miles. Here is the catch, it is a theft recovery and had the duramax and trans and all engine compartment wiring removed in the theft. I only paid $2200 for it with a clear title so I am not complaining. It is like new and I want to get it running. I have a lq9 and 4l80 with 130k and can go that route but would rather go with the 6.2l gmpp motor and 6l90.

I don't have the money for a duramax drive line and I do have this one. Work I don't mind. I am simply looking for how. Please keep the cost/ work/ get another one comments to yourself. Thanks..

Here is the idea, I currently have a brand new GMPP crate motor, 5k mile 6l90e transmission and t-case. I also have the whole electrical system, computers harness etc. from a 08 2500hd truck as well as a 04 2500hd gas truck and a 01 2500hd gas truck. I also have a whole 02 Escalade vortec max truck I can use anything out of. I also have a complete stand alone harness and ecm and tcm for this motor and transmission.

I would like to put the 6.2l into my truck along with the 6l90. I have most of the swap figured out just trying to figure out the dash,/ BCM integration. Has anyone done this? Please offer advice.

Really want to eliminate the old ecm and would like my dash to work like original along with AC and Cruise etc. If I have to I will research this all out myself. Just would like to know if anyone has already gone this route instead of reinventing the wheel myself. Don't mind using relays etc. Any pointers are appreciated. If the only things that don't work are the trans temp gauge and ac there has to be a way though this other then a whole extra ecm in the mix.

I have the fuel lines, pump, ecm, stand alone harness, motor transmission, t-case etc already, and I have done multiple ls swaps into classic stuff. This bcm integration is what is giving me that hard time.

I appreciate the help.
