Adding the 5th prong to the 4 prong trailer connector for surge brake disengaging

[Ph2426]

We have a 2022 Bronco Outerbanks and I am looking to tow a trailer with surge brakes. I had a hitch added with a 4 prong but I need the 5th wire for the surge brakes. Is there an easy way to do this? I called the company that added the hitch and they said it was not easy at all and would need to include adding a brake controller etc. I think I just need to disengage the surge brakes when in reverse. Does anyone have any tips? Thank you all

Do you have a Bronco with the LED taillights or the halogen taillights?

I have same scenario with a boat with surge brakes when in reverse, I purchased this:

Instead of wiring up a reverse light, I used the Positive from this kit to plug into the 5th reverse pin on my 5 pin adapter. Sounds like you had someone else install your hitch wiring, I would imagine they could figure out how to connect this, pretty easy. All you need is an addition positive 12V on one wire when you go in reverse to go along with your existing 4 pin connector. It gets its feed from the tail lights. Plug and play on the tail lights.

Fundamentally that 5th pin need to receive the reverse signal, so when you put the Bronco in reverse, voltage gets sent down that 5th pin to the surge break solenoid to disable it and let your trailer move in reverse.

You can buy the Curt 57187, but the blue wire on that kit needs to be connected to the reverse signal. How exactly you do the depends on if you have the LED taillights or the halogen taillights (which is why I was asking the question).

Seems like @Bearcat1 used at lighting kit to reach that reverse light signal (which is genius, by the way).

thank you both for being much smarter than me!!! I am also sorry I dont know if my rear lights are LED or hallogen. I thought the outerbanks had LED but im not sure

This is awesome. Thank you. If I purchase this do I plug this into the existing rear light and then run the wire to the tow hitch wiring?

Use the info in post #5 and #6 and that would be cheapest way out of your situation. If I was you I'd mount a 7 pin connector and wire it with post #5 solution and then use this $10 adaptor.
