Converting 4-Way Trailer Wiring To 7-Way for Tekonsha Prodigy Wireless Brake Controller Use

Question

Question:

We have the wireless brake controller on our camper and my sister wants to use it but she only has a 4 pin plug on her truck. Could we get the 4-way to 7-way adapter and then run a wire from the adapter to a 40 amp breaker mounted on the trailer connected to the trailer battery?

Yes, you can utilize her current 4-way adapter and then add the 10 gauge wire and 40 amp circuit breaker to give her a 7-way with the functions she needs. You can get everything you need in the # ETBC7 wiring kit. I've attached an article and a video to assist.

If you prefer to piece things together, you can get wire # 10-1-1 sold by the foot, circuit breaker # 9510, ring terminals # DW05705-1, and Hopkins Adapter # 37185.

With either option, you do not need to connect the brake controller output wire or the reverse wire, but you will need to connect the ground wire. This will work with the Tekonsha Prodigy Wireless Brake Controller.

We have trailer wiring that fits your 2022 Mazda CX-9 with the Tekonsha kit part #118278 but the Curt you mentioned is not a fit for your vehicle. This will work great with the Draw Tite hitch you plan on installing on your vehicle as well #76020.

To install a 7-way on your 2022 Mazda CX-9 you would first need to start with a 4-way like the Curt #C56338 which is a custom fit kit that doesn't require splicing. If the 7-way only needs to support trailer lighting function (not brakes) then…

Hey Greg! We hear that quite often about U-Haul. The Hopkins 47185 is almost identical to our item #HM47180, so if they installed it correctly you should have a blue wire ran into your 2019 Toyota Highlander's cab. If not you'll need to use…
