Recommended Brake Controller Wiring Harness and Installation Location on 2018 Nissan Titan XD


Where is the brake controller wire harness on a 2018 Nissan Titan xd ? And is there a plug and play harness for it


Expert Reply:

If your 2018 Nissan Titan XD has the factory 7-way trailer connector then there is a custom wiring harness for your brake controller. If you will be using a Draw-Tite, Tekonsha, or Reese brake controller you will use # 3050-P. For Curt use # C51382 and for Hopkins use # HM47635, and for Hayes use # HA81786-HBC. The factory harness you connect to will be located underneath and to the left of the steering column taped to another harness near the emergency brake pedal. It will be a 6 pin adapter that will mate with the 4 wire brake controller harness.

If you don't yet have a controller I recommend the Tekonsha Prodigy P3 # 90195 because of its ease of use and the diagnostics it is able to assist with to ensure it is working as desired. This controller will use harness # 3050-P.
