Im working on the harness to put a 5.3 in my 89 K1500 in my sig. Its a stock 06 harness I've been modifying.

I've gotten all the evap, a/c, O2 sensors, MAF, oil level sensor, and anything else Im not using out of it.

Now Im going through the Alldata printout stuff I have and Im at pin 13 on the blue connector. Its "Requested Torque Signal" and it leads to a plug that has probably 7 or 9 other wires and would plug into the body harness on the 06 truck.

I have no idea what that is or what I need to do with it.

Im sure there will be more I need help with so I'll keep this thread updated. But if someone that has built a harness could chime in it would be greatly appreciated!
