Why does my boat trailer have 5 wires?

Why does my boat trailer have 5 wires?

It sounds like your trailer has a wishbone harness. A wishbone harness splits the running light circuit at the connector so you do not have to run a jumper from one side of the trailer to the other side.

What is the difference between a 5 pin and 4-pin trailer plug?

5-pin trailer wiring is very similar to 4-pin wiring, but it adds in a blue wire for the reverse or backup lights. Not all trailers have reverse lights, so consider your own trailer as you wire in a 5-way plug.

Is there a 5 pin trailer connector?

If you need a 5-Way flat trailer-side connector, you can use the Draw-Tite 5-Flat Trailer End 48 Inch Harness # 20017. This connector is designed for the 5th wire to carry the reverse light signal from the vehicle to the brake actuator.

How do you wire a 7 pin trailer plug with 5 wires?

When wiring a 7-Way on your trailer with 5 wires, your green wire will be right turn/brake, the yellow wire will be left turn/brake, the brown wire will be the taillights, and the white wire will be the ground.

Can you plug 4 way into a 5 way?

Or, you could plug the 4-Way into the 5-Way end of the adapter. The extra pin on the end is for the extra function on the 5-Way, otherwise, the functions are the same for all the other pins. This means that it will function just fine being plugged into the 5-Way.

What is a 5 pin trailer connector?

5 Wire Flat connectors are typically used with marine applications. These connectors provide the following functions: left/right turn, taillight, ground and surge brake release.

Can you put red and black wires together?

These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot.

What do the lights on a 4-pin connector mean?

If it was a 4-pin connector with 5 wires then it is called a wishbone harness and would have 2 wires attached to the running light pin so you have one wire for each side of the trailer. Typically, on a 4-Way, the white wire is ground, brown is running lights, yellow is left turn/brake lights, and green is right turn and brake lights.

Which wire is the running wire on a 5-way connector?

This depends on if it’s a 5-way connector or actually a 4-Way connector with 5 wires. Just going by the process of elimination, if it’s a 4-Way the black wire would be one of the running lights circuits along with the brown.

Where does the white wire go on a trailer ground?

That white wire grounds to the truck nearby the truck receptacle. The white wire that goes to the trailer also connects to a conductive part of the trailer. The trailer could ground through the ball, but it is more reliably done through the ground wires.

How to ground a trailer with a ball?
