Question Need help Wiring harness Swap
The engine and tranny are a Complete 2009 5.3 with a 6l80e transmission from a tahoe
Has anyone done this conversion?

The truck gettin the swap is a 99 yukon.. Obs..

I know its a truck but didnt get much help in truck place lol so maybe i have better luck here...

Problem we have is how do we wire the accelerator pedal to the harness..
We bought the pedal with the harness but where does it connect to??
Do we have to splice the wires and connect it somewhere in the engine harness
I know the pedal is controlled by ecm and it dont have a separate computer like the 05-06 model trucks

The engine turns on.. gauges working already.. its on the truck ect...
we just need to know how to connect the pedal to the harness..
Thanks in advance..

There should be a plug coming out of the engine harness for the Pedal. Here is some info on a similar plug from a E38 Corvette

The pedal connector is part of the body/cab harness not the firewall forward harness.

Post a pic of the pedal & connector

Harness with the pedal connector meets up with the 12 pin connector (X205) of the dash/body harness which then meets up with the engine harness at connector X109, big multi-pin connector coming of engine harness.

Alldata says X205 is at "top left of I/P behind the instrument cluster under the defroster deflector"

Sorry don't have a truck here to reference.
