My v6 is out and the v8 is on its way in. I have been looking at were the new harness will mount into the truck harness and the dbw setup but it just doesn't look right. I cant figure out how to run the new harness through the firewall to the pedal. If anybody has done this swap please help me with pics or info. I get a feeling my harness might not work or I'm just going crazy. Please help. Truck is 07 classic 2wd 4.3. New motor 2004 lq4 from gmc Yukon xl with 4l60e. Thanks
