I have been on the hunt for electrical diagrams that are color coded for my 2012 Frontier 4x4 to no avail. Having four vehicles I do all my maintenance and trouble shooting. It's easy with my two classics but I would like to be armed with as much info as possible for the Frontier I've just acquired to make electrical diagnostics easy and understandable. Any help here? Thank you.

The factory service manuals have wiring diagrams, and are available in PDF format here.

i need the wiring diagram for the 7 pin plug in trailer lights mine. is missing the seven pin plug and the part that plugs into the round plugs under the tail light is half there. the dealer won't break up a set and i just bought it a month earlier, but i didn't have it bolted down solid. i was waiting until payday to buy the hole saws and drill bits and i got lazy.

This was as far as I got, to the connectors at the frame on the left side:

My thread is here if you work on yours and have anything to add. Still haven't gotten around to wiring my trailer lights, haven't had a need so it simply hasn't been a priority.
