I'm wanting to tow a small pop-up camper behind my 2004, C70. Rated to tow up to 3300 lbs. GVWR when uing electric brakes, 1000 lbs when not.

Trailer has electric brakes which I would like to take advantage of. Anyone had any experience installing one of these and want to pass on some helpful hints? Most specifically, I'm looking for the correct wire for input into the controller a the rest of the installation is pretty straight forward.

Thanks.
