With your travel trailer jerking right or left at random, I can only tell you what to look for but can't diagnose your issue. I am not at all physically familiar with the Hensley system but from what research I have done it seems like the system could be the issue. The description of the unit in their videos show that the impact on the trailer for wind is directly transferred to the tow vehicle to help absorb the sway. The theory for this is good, but if you have a shorter wheel base... view full answer...
If the lights are functioning properly when the vehicle is on you're totally fine to either ignore the problem (if you can) or unplug the trailer wiring when not in use to prevent it from happening. Unfortunately it only takes a fraction of an amp to light up an LED so the small bleed through on your circuits is going to light them up here and there. i would still try load resistors like the Diamond # DI34ZR view full answer...
Sharp turns combined with too much weight for the system and L-brackets that are very tight can cause the brackets to bend. Make sure that the trailer weight does not exceed the capacity of your system and that the spring bar hangers are positioned the correct distance from the ball as indicated in the instructions for your system.
Be sure to check the tongue weight of the trailer when loaded and ready to to and then add the weight of anything loaded behind the rear axle of the tow vehicle... view full answer...
Since your 2016 Ford F-150 XLT has the factory trailer brake controller port underneath the dash for plug-in wiring harness # 22292, you do not need to run a 30-amp inline fuse for the Tekonsha Prodigy P2 # 90885 to work correctly. That is only for vehicles that do not have a factory trailer brake controller port.
I recommend testing the black wire on the back of the controller using a circuit tester like # PTW2993. This is the power wire for the trailer brake controller. If you are not... view full answer...
I would recommend checking the fuse box in your friends F-150 to make sure it has the fuses/relays installed for the trailer stop and turn lights. I looked up a fuse box diagram for a 2011 F-150 and it looked like the trailer tow left stop/turn relay is at location 37 and the trailer tow right stop/turn relay is at location 38. You will want to check the legend in the fuse box of your friend's vehicle to make sure those are the correct locations.
I would also recommend using a circuit... view full answer...
This is actually a fairly common issue with the Demco Stay-IN-Play # DM86VR, and there are solutions.
Since the turn signals and brake lights normally use the same wires, they use variable voltage to activate each circuit. The system is seeing a signal less than 12v and is trying to activate. What you'll need to do is reset the GFC (G-force controller) slightly to the "more" position. Then, go through the GFC set-up again which is step 12 in the instruction manual. This time, raise the... view full answer...
There are a couple things to check but it could be a fuse that needs to be replaced on your 2009 Ford F-150. The first thing you can check is the connectors on your truck and trailer, make sure they are free of debris and clean.
On the trailer connector test the pin at the 5 o'clock position with a circuit tester like the Circuit Tester Kit

The Tekonsha Prodigy P2 Trailer Brake Controller part # 90885 can be reset by pulling power from the controller via the plug on the rear and then waiting a few minutes before reattaching which it sounds like you have done. This would have then cleared any errors on the brake controller. The constant output error could have been caused by either a wiring short or an internal short in the brake controller. I recommend you look over the wiring on both the tow vehicle and trailer. If all is... view full answer...
I was able to reach out to my contact at Wilmar who mentioned a couple of different things that could be going on with your 2.5 Watt Solar Battery Charger # PTW2997. First, they mentioned that you should always use the battery end that came with the solar charger, so if you've not connected the solar panel with the cord that it came with, this is the most likely culprit. If that's not the case, they also mentioned to look at the following things:
- make sure that the battery it is being... view full answer...
I think this might be the ultra-rare Ford dummy harness issue. A few years ago I had a customer with a similar problem. It took days of troubleshooting and a savvy Ford tech at a dealership to determine that the harness behind the dash that the controller plugs into was not a complete harness so that could be what is going on. Ford would have to provide the harness.
If you have the correct harness, which is likely given how rare this issue is, then it could be another problem with bent... view full answer...
A great way to test the brake controller blue wire output is to use a Circuit Tester, like part # PTW2992. You will want to test the blue wire at the back of the brake controller. If that is low, then there may be an issue with the vehicle wiring. The bulb in the tester will place a load on the wiring, and you can tell if you are getting full voltage by the brightness of the bulb in the tester.
If you find that the bulb is dim with the brake controller set at maximum setting, you will... view full answer...
You may have a bad relay in your 2012 Ford F-150. Under the hood in the power distribution box check the relay in location 37. The easiest way to see if a relay is bad is to use a known good one in its place. You may have to get this relay from a Ford dealer. view full answer...
When a brake controller says that there is no trailer attached even if there is a trailer attached that means that it is not sensing the brake magnets. This could be because of a problem on the brake output wire such as a severed wire. It could also mean there is dirt or corrosion on/inside the vehicle or trailer side connectors.
There are some tests you can do to determine where the problem is. In the truck cab you will need to sever the brake output wire several inches from the back... view full answer...
It sounds like you need a brake light relay kit. This kit is used to prevent the towed vehicles brake signal from overriding the turn signal from the RV when applying the brakes during a turn.
For this, you can use the:
-Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400.
I have also included an installation video for you to check out as well. view full answer...
From what Hydrastar tells me, the Ford OEM brake controller for the 2013 model year is compatible with Electric Over Hydraulic (EOH) brake systems, assuming everything's operating correctly.
I'd begin by testing the OE brake controller. Have a helper pull the manual brake switch as you test the pin in the 5:00 position on your 7-way with a circuit tester like # PTW2993. With the ignition on, that pin should show output with the manual brake switch engaged. If it does not, you'll want to... view full answer...
You have done a really nice job of narrowing down the possible source of the trouble you're having with the trailer lights and the lights on your truck when connected. There certainly seems to be something going on with that brown tail light circuit wire running down the right side of the trailer.
Since you tested the 4-Way on the truck you know the truck's wiring is good. What I recommend doing, and this may be a bit of a pain depending on how the wire is ran, is to try and trace that... view full answer...
As you suspected, you have a poor ground connection at some point.
It is important to have a continuous ground connection from the tow vehicle, to the trailer and continuing on to the trailer lights. The trailer connector on your F150 needs to be grounded to clean metal. The connector on the trailer will be grounded to the trailer frame, usually on the trailer tongue. Make sure this connection is clean and free of corrosion. The trailer lights will receive their ground connection either... view full answer...
The first step for troubleshooting your 4-pole installation is to check that the lighting functions on the vehicle itself are operating correctly. This needs to be checked first since the part you referenced, Draw-Tite 4-Pole Hardwire Kit # 18252, relies on input signals from the vehicle lights to send output signals to the trailer. If the vehicle lights are not working properly you will need to get those fixed first. Once you have confirmed the vehicle light functions are all okay you... view full answer...
My tech contact at Furrion has seen connectivity issues like you're having with your Furrion Vision S observation camera system # FOS43TASF. He said that late model vehicles and/or trailers that have highly-efficient LED lights may not use wiring heavy enough to fully power the transmitter on the camera. The fix for this is to use a direct battery connection and a manual switch like # PK34308 for delivering operating power to the camera, rather than the clearance light circuit on the trailer. view full answer...
