Yes, a 5-way trailer connector can be used with trailer brakes. You'd have to make the 5th circuit of the 5-way the brake output circuit and you'd be set. Normally this is used for a reverse light circuit for a reverse lockout circuit but if you wired it up to be a brake output circuit it would work perfectly fine.

Hi. My boat gas surge brakes that utilize the 5th pin, reverse override. I’m looking to buy a box trailer with electric brakes, with a 7 pin, round. Can I use a 5flat to 7 round adapter to engage the electrical brakes on my trailer? Or, do I have to change something on my vehicle side to engage this? If so, what? And If I do this, would I then lose my surge override for my boat? Thank you.

@Chad If your 7-way has all of it's circuits active the reverse light circuit is there and would allow you to simply plug in a 7-way to 5-way like the part # A57WB and the reverse lockout of your surge actuator would engage like it needs to. If the circuit is not active you'd just need to run the center pin of the 7-way to your reverse light circuit.

Your Tekonsha Prodigy P3 #90195 on your 2004 Toyota Tacoma is showing no trailer connected because you only have the 5-Way flat connector on your trailer. The 5-Way carries the basic trailer light functions and that 5th pin is typically for the…

If you are looking for a way to power the trailer brakes you would not run the blue wire of the 7-way to the positive post of your battery. Instead you would run that wire up to the blue wire of a brake controller like the part #90885 that you…

Electric brakes have 2 wires located at the back. One is for power and the other is for ground (it doesn't matter which is used for which function). The ground wires should be connected to the trailer frame. The only other place that would carry…

If you are referring to two white wires from the brake magnet that are coming from the rear of each electric brake assembly, then it would not matter which wire is connected to ground and which wire is used for the brake feed. The magnet that…

It sounds like you're looking for a trailer side 5-way connector but your picture is of a 7-way. If you're looking for a 5-way we have part #HM47910 that has a nylon sleeve covering the wires to protect them. I've linked a video for you…

Answer 11

In order to actuate the trailer brakes, you'd need a brake controller installed in the vehicle and a 6 or 7-way trailer connector. A 4 pole flat wiring harness like the #18002 you'd looked at carries 4 circuits- right turn/brake lamp, left…

Answer 12

I have a solution for you to consider, but there are no adapters for a 5-way round. What you can do though is just cut off the 5-way round on your boat trailer and wire in a 5-flat, the 5-Way Flat Trailer Connector #HM47910. Then what you can use for…
