I bought an old cargo trailer. Put a new 4pin connector but the tail lights keep going off when hitting the brakes. Checked the grounds but seem alright. Any ideas?
Start by testing the 4-Way connector on your tow vehicle. If you see the tail light pin not showing power when you press the brake pedal then you either got the wrong 4-Way, it was installed incorrectly, or it needs to be replaced. If the tail light pin still works fine when you press your brake pedal then that means the issue is on your trailer and you're going to want to look at all your wiring and connections for any places where the wires are damaged or bent. It's also good practice to check out your connectors as well for any corrosion or debris.
I recently installed a new hydraulic brake actuator hitch on my boat trailer. I would like to wire in a plug for the automatic brake lockout solenoid that came with it. It has a blue and a white wire attached to it. I assume the white wire is a ground. It appears that my four-prong plug will not allow me to use it for the back up light activated device. Please advise me on my best course of action. Thanks.
It sounds like you already have a 4-Way connector setup for your tow vehicle and trailer and that you are needing to change it over to a 5-Way. To accomplish this you can use the Hopkins Endurance # HM47890 . You will connect the 5th wire for the tow vehicle side to your reverse light circuit and then the 5th wire on your trailer side to that wire on your hydraulic actuator.
I have a Ford Transit 350 & a Wells Cargo trailer. The Wells Cargo trailer has an internal junction box where all the lights tie into, but I "believe" also has relays/switches in it. Is this necessary as don't most wiring go directly to the lights? Now does it matter that the trailer lights are LED & not incandescent?
It would be a little unique to see a bunch of fuses for your trailer wiring on the trailer side of things. Your vehicle will definitely have fuses dedicated to these functions though. So I wouldn't say it's necessary for standard trailer lighting (whether LED or Incandescent), but there really isn't any harm in it either - it would actually provide you with an extra layer of protection. It doesn't matter whether the lights are LED or incandescent, but we do recommend having them be the same type of light.
My old trailer connector has 5 wires into it with 4 pin connector. Bought a replacement flat pin connector. It is a 4 pin , but only has places for 4 wires.Replacing connector on truck side.
I've heard of this on a trailer before where the running light signal is run on 2 different wires so you can route that wire down both sides of your trailer, but I don't think I've ever heard of that for a vehicle-side connector before. The only time that something like this would exist is if there is a stop light that needs to be tied in, but even then the 5 wires would run through a module and wouldn't all be connected to the 4-Way. What is the year/make/model of your pickup, what functions do those 5 wires carry, and what connector did you purchase as a replacement?
Replacing tail lights on 1977 Shasta but color wiring is 1 white 2red it had two bulbs I assumed top bulb was brake bottom two wires are running lights and turn signal but all I get is a dim flashing. Help
You need to test the wires that are on your 1977 Shasta and then connect them to the correct wires on your tail lights (I'm guessing you just replaced them). Typically white is used as a ground but this isn't a rule that's set in stone which is why you need to do some testing.
Thanks for information. This answered my question!
Change subject! Need to hookup tail lights on Ford Fusion to operate when being towed by Motorhome. 4 way flat harness
If you have a Titanium Model you can use # RM-154 . This kit will wire into your factory tail lights, providing a nice clean look. If you have a Hybrid or Energi model you can use # C6304 . This will mount with strong magnets on your trunk and are designed to not scratch so long as the surface is clean.
