I have a 2008 Armada SE that did not come pre wired to the back of the car for trailer lights. I purchased all the parts I need such as relays, harnesses, etc. The only thing I'm having a hard time with is the harness that goes from the relay box? to the back of the car, part number 24167-WR8SE. One end has the plug for the 7-pin adapter that my harness connects to at the back of the car, the other end has 7 wires that need to be connected somewhere to power them. I have searched the forum and haven't found what I'm looking for. Could someone please point me in the right direction for where those wires get connected? Thanks!
