Need brake help!


New Member
Just bought a salem cobra fifth wheel. 93' tandem electric brakes. Dog at this house chewed up the wiring against the drivers side drums really good. My questions is : How can I tell which wire going into the "hub" is positive and negative? For some reason I believe they need to be parallel.

It really doesn't matter because its just an electro magnet in there. the power can flow backwards and the magnet still grabs.
