Ya, I have noticed that it is "the road less traveled" or at least as far as the information I can find is concerned. However I do not have the cash to buy a harness right now, and I already have this donor harness. The VATS have already been tuned out of the ECM.
I did some more research tho, and am of the conclusion that the module in question in actually the TCM. I was under the impression that this truck had the 6 speed, which has the module inside the transmission. But then again I have been wrong quite a bit, lol. I am going to remove this from the harness as the swap vehicle is going to be a manual.
I am in no rush to finish this project and would like to work with what I have. But I am struggling with the wiring, as far as what to pull from the donor truck to make it run, such as the throttle pedal and wiring. I believe there should be a TAC (Throttle Actuation Module) on the fIre wall, but I cannot see anything there. I am disassembling the dash right now looking for modules and harness components that I will need.
