Review on ACDelco GM Original Equipment Trailer Brake Control Switch Assembly - Black Carbon, Part Number 23476237 by Nathan Skipper

ACDelco Trailer Brake Controller/Transfer Box Switch/Light Control Panel, I bought the panel to add a REDARC Trailer Brake Controller System to my truck as they are NOT an OE brake system add controller if it was not originally used on your truck. My original panel has a storage pocket where the OE controller should be. I prefer to retrofit a replacement panel if I ever need to remove the aftermarket controller.
