gwtriker Report post Posted November 4, 2019 I have an old EPCO ESSBC brake controller that I want to use, but I do not have the wiring information for it. Does anyone have this information they can share. There are 5 wires, red, black, green, white and blue. I'm sure the white ground and the black is 12 volt power, but not sure what the others connect to. Thanks for any information you may be able to supply.

jleamont Report post Posted November 4, 2019 Blue is the power line to the trailer brakes, red is typically the ignition feed. The Green is throwing me off, that's a new one... Assuming this is an trailer electric brake controller? Is there a model number associated with the unit? ESSBC and neither is EPCO for a manufacture isn't coming up on a quick web search.
