Brakebuddy Classic Power Plug wiring

[2weeks]

My power cord has come loose from the 12v plug (no full disclosure on how it happened). I would like to reattach it to the plug but can't figure out the wiring connections. I couldn't find enough detail on the Brake Buddy website.

Can anyone help? Thanks.

You will have to open up the case to be sure which wire is the positive and put a new end on. I removed mine and wired a 2 prong plug and hooked it directly to the coach battery

I had that happen on an even brake I used to have. One wire had a rib on it. I emailed Roadmaster and they emailed me back that the ribbed wire was positive.
Moral of the story. Ask Brake Buddy.
