trailer electric question

[BPrifty]

I ran into a situation recently and as a towing rookie, I could use some advice. I had rented a flatbed trailer to move some vehicles and equipment to my new home and found that the trailer wiring harness on my truck was not compatable with the trailer I had rented. The rental trailer was a small 6 pin assy and my truck has a large 7 pin assy (stock I think?), so I purchased an adapter, got all hooked up and found that the trailer brakes would not unlock. The slackjaw lot guy helping me out said that this was common problem with Dodge since their trailers are wired for Fords. Anyone familiar with this situation and possibly how to rectify it? Any help would be appreciated!

Very quick and simple fix. There are two positions you can use on a 6 prong for trailer brakes. The center pole or the one marked A/S. Undo the small screw on the front of the 6 prong plug and push out the wires and connector. Then just move the trailer brake wire to the center or A/S, whichever is not being used. Should solve the problem.

There is no difference in stock wiring among any factory wired vehicles. That guy either didn't know what he was talking about or they wired all their trailers according to some Ford that was not wired correctly.

all trailer wiring is standardized.

Its all in the cheater plug

I work for govt. and we get new Fords and Dodges every year. We have alos found some cheater plugs do not work between brands. We have always found the factory cheater plugs always work. The aftermarket plugs are brand specifc. Some of these plugs are not hard to take apart and change if needed.



DO NOT CHANGE YOUR FACTORY WIRING!



The factory 7 prong "RV" plug is universelly wired. It is not the problem.
