Trailer Wiring on a 1997 Ford Explorer Stopped Working

Expert Reply:

If the Tow Ready Custom Fit Vehicle Wiring, # 118345, was working on your 1997 Ford Explorer but then suddenly stopped working, the first thing I would check is the fuse that came with the converter. The power wire should be connected to the vehicle battery via the fuse and fuse holder. If you find that fuse is blown you will need to replace it.

However, if there was a short on the trailer wiring, trailer side, or corrosion in the connectors on either side, it could blow the fuse again.

Loss of a ground connection could also be the issue. Make sure the converter is attached to a clean metal surface.

If your Explorer came with a factory tow package that included a wiring harness, you would need # 118241 as a replacement. If the factory harness stopped working, you can check the owners manual for a legend that shows where fuses/relays are for the tow package wiring to determine if those need to be replaced.
