There are many different ways that you can connect the 4-pole connector on your trailer to the 5-pole connector on your vehicle. If the 4-pole and 5-pole connectors on your vehicle and trailer are the flat style connectors, then you could simply plug the 4-pole trailer connector into the 5-pole vehicle connector. Doing this would leave one slot exposed on the vehicle 5-way connector, but that slot is usually attached to the reverse light circuit which you do not need. In some cases the connector on the trailer may have extra plastic molding that may not make them directly compatible, but you could replace the connector or use a utility knife to trim down the extra plastic.

Another option would be to add a 5-way connector to your trailer like part # HM47910. This would give you the additional connection if you wanted to add brakes to your trailer in the future. If you did not want to add trailer brakes, then you could simply tie off the brake wire and tuck it away. This would give your trailer a 5-way connector like your vehicle.

Hi the trailer wire plug on my truck has a 4 female connector (receiver) and the boat trailer that I need pull has a 5 pin male connector. Will this plug set up still work?

The two plugs will still physically connect and work to power the trailer's signal lights - but I'm assuming the boat trailer uses a reverse lockout solenoid (so the brakes don't engage when backing up). If this is the case, you wouldn't have this function when hooking up the 4-Way on your truck to the 5-Way on the trailer. What you can do though is add an adapter like the Tow Ready # 20036. This would just plug into your existing 4-Way to provide a 5-Way at the other end to connect with the trailer. The additional blue wire just needs to be spliced into the reverse circuit wire on your truck to activate that function on the 5-Way.

Answer 1

You will still be able to use the trailer with the 4-Way after installing the 4 to 5-Way adapter, #20036. First, you could just remove the adapter if you wanted to and then plug in the 4-Way like normal while stowing the adapter in the truck. The…

Sounds like what you are looking for is a high low adapter like part #RM-070 which will allow you to raise or lower the hitch height by 4 inches. I also attached a link below that shows how to pick out the correct high low adapter as well.
