Also, I would run your ALDL into the cab of truck rather than under the hood, will make difficult logging if you ever decide to have it tuned properly.
Also, why did you guess at the wiring of the O2s, they are quick connects, was your harness cut up? and make sure you have the FRONT O2s and did not wire them into the REAR O2s.....
I guess because they are NOT quick connects. they are blank/cut wires out of the box with crappy diagrams. however, I did figure out that two if the wires on the drives side were swapped. It s now correced and running like a champ. Thanks for all the help
