After towing my reg cab last weekend up some hills & not having a O/D lockout switch I figured Id install one this week
got the instructions off Kennedy's website, got the parts from radioshack
wired everything up, went for a ride & nothing
figured the tcm had an updated calibration(was OS - 15172881
CAL - 15172880) since the tcm had wires coming out of it from the previous owner, I extended what was there
updated the calibration to OS - 15172881 CAL - 15172884
still nothing
pins are in the right spots, have power to one side of the switch, gets momentary power on the other leg of the switch

am I missing something here? I just dont get it
