Was digging around the jack compartment in the trunk and came across this harness. Does anyone know what its for?

this is the harness that plugs into the electric brake control harness plug under the drivers side panel and the other end you connect to an electric break controller they make premade ones now so its plug and play to certain controllers.

If you use that one you have to splice into the wires on one end. Most controllers come with a plug & play harness, no wire cutting required
