Were do the two wires on a brake away control conect to wiring harnes on a travel trailer

Hi. Thanks for your question. For the diagram of Tail Light you can visit https://www.reliable-store.com and download the entire workshop manual. It has all the information along with the diagrams for better understanding. Good day!

Get a shop manual. If you're putting in a trailer harnes, try a uhaul center. They do it all the time and much cheaper than the dealer.

there will be only 1 power wire for the brake lights as they are connected .together. What you are looking at are the indicator lights (1 left wire and 1 right wire)

Hi Frank,
I have a Durango 2000 and pull a 24 foot ski boot loaded with equipment. I don't know about you, but I wouldn't try towing anything without the trailer brakes connected. I purchased the Titan Trailer brakes setup and they've never failed me once. The hitch: just make sure you get the right towing capacity for your travel trailer. I have the 5.9 liter engine, which allows up to 6500 pounds of towing capacity. Your owners guide will explain how many based on engine size.
Good Luck, and happy traveling.
Mark

Under the pan on the drivers side u can install the proper harnes for your trailer. The maim post for trailer brakes is on the front fuse panel under the hood.If you are running your own in line trailer lights...........I would start at the main break away dis-connect.

I have the exact same issue. I have also tested my trailer on other vehicles and it works fine. I even purchased a light up tester and found the problem at the harness. It seems like a bad ground to me but I can't seem to find one.

The trailer lights have a common brake/turn wire while the truck has seperate turn and brake lights. I think the problem lies with the device that marries the two for the trailer wiring but I don't know where to find it?

i have a 2008 ford f250. when i pull my travel trailer the instrument gauge says trailer disconnected and it also says trailer wiring malfunction. then my trailer brake systems turns red and blinks. i took my ford to the dealer they said the truck is fine it is the trailer. than I took my trailer in to get looked at they said the trailer is ok and that 2008 fords have problems with the stock electric brake system what do i do

You can purcahse a tester which will connect into the F-150's wiring harnes. If the led lights up, the problem is witht he trailer's wiring harness. this tester will indicate the proper operation of the brake light and turn signals.

Try looking at this link. If it makes sense, great. If not, we'll try to get the actual 74377 manual.
