Make certain that the wiring is connected properly but also, check the ground wire. Don't count on the hitch to be the ground for the trailer. There should be a ground wire that goes to the electrical plug, make certain that it is connected properly.
Many auto parts retailers will have a plug-in trailer connection that is designed specifically for your vehicle. If they do, it's usually just a quick process of following the directions. It's worth it especially since it can help you keep from having the connections corrode.
No, the license plate light is wired in with the rear tail lights, not the brake lights.
replace fuse
I think I can answer my own question. Went to walmart and found a brake light for a tow hitch, with a logic circuit on it for $10. I also purchased a converter from a 7 way trailer hitch plug to a 4 way, which is needed for the trailer hitch light. It also was $10. so I will tap into the logic circuit to the third brake light. for $20 it solved my problem. Thought I would pass this along.
1) I've learned more than anything to unhook the lights before backing the trailer into the water. Nothing like a hot bulb meeting cold water.....but if you believe the advertisements, boat trailer lights should be waterproof and not let water into the space where the bulb is. RIGHT !!!! 2) Now, the other issue that has to do adequate grounding usually needing more just the hitch ball. - inadequate grounding is the number one cause of trailer light problems and cause all kinds of strange behavior (work sometimes, or only when headlights are off, or both sides flash with either blinker, etc.) - try a better ground than the tongue and checking for any corrosion at any of the individual light ground connections (which tend to corrode over time).
Your trailer tailights are dual-filament, with one being the running lights and the other the brake lights. You need a separate power source from your towing vehicle's brake lights to power them. The easiest way to do this is go to U-Haul and but a set of their trailer towing taillight bulbs for your towing vehicle. The bulbs replace your standard tail/brake light bulbs, and they have two wires coming out of the base of the bulb. One of the wires connects to your trailer's running lights, and the other one connects to your trailer's brake light circuit. I'm trusting that when you re-wired your trailer, you ran two wires from the taillight socket, one for the running lights and one for the brake lights. In some trailers, the brake light circuit also doubles as your turn signals. Good Luck.
There are no extra fuses for your trailer lights. If you have the towing package (and you do) the trailer lights run through your regular fuses (tail, brake, turn).
I would check the running lights for one with a short. I had the same sort of thing with my trailer and I spent way to much time troubleshooting the brake and signal wires. Turns out a running light bulb connector was grounding out on the trailer and messing it all up.
there may be a short get longer wires
Tail lights and brake lights fuse.
You have a poor or no ground between the vehicle and trailer.
