Where Does Blue Wire of 7-Way Kit for 2015 Dodge Durango Go

Published 07/09/2019

Question:

Beginning underneath vehicle, on driver’s side, route body harness with red/black/blue wires forward. Route harness over rear wheel architecture and over to passenger’s side. Then following existing wires route red/black wires to positive post underneath hood. Route 12 gauge blue wire to vehicle body harness connection point. Connect to vehicle’s green wire, using supplied using butt connector. Q: Where is the green wire located on the vehicle.. specifically? There seems to be several vague answers. Also can you briefly explain the function of the blue wires so it is clear how to test to find correct wires to tap into? This 12 gauge also states to use butt connectorinch so this doesnt seem to be a splice.. correct?

The blue wire of the 7-way kit part # TK22113 goes to the reverse light circuit of your 2015 Dodge Durango. The good news is that if you trailer does not need a reverse light circuit you don't have to connect this circuit but it's there in case you do.
