Some bad news, I looks like I through away the section of harness going to the gas pedal. I saved everything, but when cleaning up a few months back I tossed what I thought was not needed.
Plan it to hit the junk yards and fine what I need.
The vans are different than the pickups. In the vans all the wires go into the main harness, I cut mine in two as I could not push the wires out.
The trucks have a harness that looks like it would work better as it just pedal wires.
