Trailer Wiring - Back Up Lamp Warning
SOURCE: Honda Service News
TITLE: Back-Up Lamp Circuit Can't Handle Additional Load
APPLIES TO: 06 Ridgeline
SERVICE TIP:
The 7P trailer connector for the '06 Ridgeline doesn't support back-up lights, even though the connector schematic that's molded into the connector cover
says Back-Up Lamp. Don't add extra back-up lights or accessories to this circuit; the wiring and switches can't handle the additional load.
