Question:

Watching the video of installing ETBC7 on 2012 E350. Does the adapter harness from manufactures plug to brake controller come with controller or do I need to order that separate. If so do you have the part number? Thank you

Expert Reply:

If your 2014 Ford E-350 van came with a factory installed 7-Way or 4-Way trailer connector then it will have a port to plug in a brake controller. The harness you will need is # 3034-P for Tekonsha brake controllers. I recommend the P2 # 90885 because it is easy to set up and use and it is reliable.

If you do have the factory 4-Way then you will also need to add a 7-Way using # 37185 to complete your wiring. The brake (blue) wire will need to be manually run from the brake controller back to the plug in the rear though. The brake controller power supply and brake pedal wires are already run.

If the van did not come with a factory trailer connector then you will not use # 3034-P at all and instead will need to hardwire in the controller using # ETBC7. You will also need to install # 118551 prior to installing the ETBC7.
