So this is a 2011 Yukon XL 2500 and the donor is a 2011 Duramax LML. I have modified the fuel sending unit to fit the yukon gas tank thanks to Bamfm7 and test-drive in another thread. I have a buddy that will do the dual tank tune in EFI Live for me. The drivetrain is installed and I am almost ready to put the body back on, then the work begins!!! I will post pics on what I did with the filler neck setup, I did a lot of reading and it seemed there was lots of trouble with filling it up at a normal speed without the nozzle kicking out all the time or diesel spitting back up so hopefully this works ok.

Couple questions before the body goes back on, I have read the ABS/Stabilitrak module must be changed. Is this a communication thing with the ECM from the duramax and can this be fixed with a tech 2 or is it just better to swap it? Here is a picture of the ABS/Stabilitrak Module.

The other question I have is about a connector from the harness that goes down to the transmission, there is a little tail of wires that comes out and plugs into another connector from the wire harness on the frame of the Yukon. It is just before the ABS/Stabilitrak module towards the front. Here is a picture. The connector on the left is from the duramax tranny harness and the one on the right is from the yukon harness thats on the frame. Pretty big difference. Does anyone know what these wires do?

There are seven wires on the yukon connector that goes to the rear of the vehicle somewhere.

Probably would be easiest to swap the ABS controller as it's programmed to the vehicles VIN.

Gas ECM Harness

I'm putting the ECM Harness Drawing here to see if anyone can guide me!! This is about the connector issue and picture I put above. I will put the Diesel drawing next.
