I have a 2006 silverado 4.3l factory
Swap it to 5.3l out of 2005 Yukon
Came with harness and computer
No gas pedal.
A shop was doing the job, but they gave up on me.
Truck is at my house now, and I'm trying to finsih it
Truck is doing weird things. I can explain
If yall can please help me to what I need to buy or do, I will do it.
Thanks
