Where to find the Electric Brake Wire on a 2006 Ford E250 Van

Question

Question:

I have a 2006 Ford E250 and I am trying to find the blue electric brake wire in the harness that comes from the plug under the dash. I purchased the controller, hitch, and plug from your company. I may have to stop at a dealer and get a wiring diagram. Please help me find the diappearing blue wire.

If your Ford E250 Van is equipped with the under dash plug for installing a brake controller that matches the Brake Controller Wire Replacement for Ford, item # 3035-P, then the blue wire should be terminated along the inside driver side frame rail near the spare tire, at the rear of your van, see photo.

Many times there is a connector there and the blue wire will enter the connection but, is not continued on from that point. You would need to connect the blue wire from the Adapter 4 Pole to 7 Pole and 4 Pole, item # 37185, to this wire using a quick splice, item # SWC501915-1.

If you cannot find the blue wire at this connector, it is terminated somewhere in the wiring harness between the back of the vehicle and the connector under the dash. If this is the case it is much simpler to run a new blue wire, item # 10-1-1, from the blue wire on the adapter to the blue wire under the dash of the vehicle.

You should check the connector under the dash with a circuit tester, item # PTW2993, to see if it is fully functional. You should find a ground terminal, a constant 12-volt power terminal, a brake signal terminal that goes hot when the brake pedal is pressed, and the terminal that the blue wire carries power out to the trailer brakes.

If the under-dash plug is not functional, or not there, you will need to hard wire the brake controller using our brake controller installation kit, item # ETBC7. This kit contains all of the wiring, circuit breakers and connectors needed to complete a professional installation of a brake controller. I have included instructions for hard wiring a brake controller for you to review below.

All of that is not necessary. All you have to do is lock out the surge coupler so it cannot move in and out or disconnect the brake lines. By removing the old coupler you would have to remove the brake lines any way. A surge coupler can still be used…
