Contact whomever made the harness and ask them how to make it work. Surely they knew what they were doing when they wired it up.

I have at least once and didn&#39;t get any clear anwser. I know know after a few more checks with actual trucks with this set up and there is at least one wire missing. The buy who made the harness thinks that the 4x4 harness is the same between the 1/2 tons and the HDs and that there is a different shift control module and a few speed sensors between the two. My fear is that he is wrong and I&#39;ll need to pull the whole harness out and have him remake it.
