I see that there is hardwire and TUTD enable, but what pin? I have a the resistive ladder diagram needed to make it work, from a GMPP connect and cruise 8 speed kit. But I don't have the harness or diagram for it? All it says is blunt cut, wire to trans harness. If anyone has a harness they could use a multi meter to find the pin?? GM harness kit 24284055
