I have a tow package and the 7 pin on the bumper is already hooked up, came like that from factory.

I don't have a brake controller and I am installing one. My only problem is finding the brake control wire under hood. I think its already installed but need clarification.

Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.

You should find 4 blunt cut wires together.

  1. white ground
  2. light blue/white brake input signal
  3. red/black power
  4. dark blue brake wire to the trailer connector

The wire diagrams show these wires on the left frame rail where the cab and bed meet.

I'm referring to the 2 red wires typically found near fuse (1) and brake boost (2) the first red wire USB the brake control wire and the 2nd is the 12v wire.

This is under the hood. The 4 blunt wires you speak of are found under my dash not the hood.

Can I get your vin#?

Your wanting all the wires to connect to an aftermarket trailer brake controller, correct?

You need power, ground, brake signal in and brake signal out, correct?
