That is correct. Your 2017 Ford F-150 does not need an adapter when converting trailer wiring from incandescent to LED. I attached a page that has all of the LED trailer taillights we offer.

We do have the Hopkins Trailer Connector tester part #HM50928 which will allow you to plug your trailer's 7-way into it and test all of the circuits easily. I attached a review video for this product for you to check out as well.

Answer 3

That is definetly unusual for all of the lights on the Hopkins 7-Way #HM48503 to be on at the same time, as that would mean that power is getting sent to all of the pins on your vehicles 7-way connector at the same time. Since there are no lights…

Most likely the fault code is due to a wiring issue on the 5th wheel trailer. The first thing I would check is the wiring on the trailer for any breaks of splices that could be causing the short. Next I would make sure there is no corrosion inside or…

Answer 8

The brake output pin of your 7-way (5:00 position) should not have voltage on it all the time. The only circuit that should have voltage all the time is the 12 volt accessory circuit which is in the 1:00 position. You'd need to look for a short…

Answer 10

My suspicion is that you have a poor ground connection somewhere on your trailer. The fact that everything works fine until the running lights are turned on is the dead giveaway. When the tail lights are turned on, the trailer lighting is drawing…

Answer 11

When a trailer's tail light remains on when the vehicle is shut off, this usually indicates some kind of short in the wiring. I first recommend using a circuit tester like #PTW2993 to check the vehicle side connector. You will want to see if…

Answer 12

If your trailer has 7 wires running all the way back to the brakes, then yes, you can tap into the existing wiring. Each of your new brakes will have two wires for the brake magnet. One wire is for 12 volt power to the brake magnets and the other…
