How to Determine the Functions of a 6-Way Trailer Connector

Question:

Id like to eliminate the 7-way to 6-way adapter I am currently using and would like to buy a cord with a 7-way on one end and 6-way on the other. Looks like the difference between Blue Ox BX88206 and Hopkins HM47053 is the center pin wiring on the six way brake vs. 12V. My question is, I dont know how my jeep toad is wired, and I would prefer the Hopkins center pin brake, will the Hopkins work?

The only way to know for sure which way your 6-Way connector is wired is to test it with a circuit tester like # PTW2993 if you do not already have one. You will have someone sit in the vehicle and turn it on. Then test the center pin. If it is hot, then you know it is the 12-volt circuit. If not, then it is either the brake output circuit or the 12-volt circuit is not live.

If you have a brake controller have the assistant apply the manual override while you test the center pin. If the center pin is live and connected as the brake output circuit, it will light up the test light.

The other way to determine the functions of a connector is to trace the wires leading from the backs of the connectors to where they terminate.

You can then choose the appropriate cable.
