5-Way Connector Recommendation for a Boat Trailer for Reverse Lights


Hello, I am wondering if anyone makes the exact opposite of product #20036 Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter. I need one that has 5 pole males, 4 pole females and the extra male wire. I know that must sound dumb but my truck is a 7 pole, my boat trailer is a 4 pole and I want to just add a separate 5th wire so my boat trailer can have reverse lightsthus the need for the opposite of #20036. I already have a 7 to 4and5 plug-in adapter. So does any such thing exist? Thank you.


Expert Reply:

An exact adapter like what you are looking for doesn't exist, but I do have a better solution for you.

You would want to cut off the 4-way on your boat trailer and then replace it with a 5-way like part # A25W5B. You would want to cut all but the blue wire short with this connector and then match it up to the 4-way wiring you have on your trailer.

With the blue wire left long you could run it to the reverse lights on the trailer.
