Question:
trailor plug in 7 way - are the plug in functions the same regardless of trailor brand
asked by: Clutch
Expert Reply:
The function of trailer connectors are often similar, as evidenced by the accompanying diagram which shows the functions of 7-ways. It really depends on how the connector is wired; that said, there is an easy way for you to determine the functions of a connector.
All you need is the Hopkins Tow Doctor Trailer End Test Unit # HM50928 in order to test the trailer-side 7-way.
I have also added a link to a help article on trailer wiring which I strongly recommend checking out.
