Where did you tap into ignition on power?I have both the original 4 pin and I added my own 7 pin.
(4 pin moved, and yes I'm missing a screw, lost one during install, no biggie and has been low priority to find a replacement)
4 of the 7 in the 7 are identical and are interconnected. You'll need to add 3 additional wires only.
1 continuous 12 volt power (or switches on with ignition)
1 for trailer brakes led to brake controller in cab
1 for reverse lamp on trailer (optional and if so equipped).
