Roadmaster Single Park Light Diode Installation - 2003 Jeep Wrangler- Video
Today on this 2003 Jeep Wrangler, we're going to install part number RM-690. This is the Roadmaster Single Park Light Diode. The idea behind these diodes is to prevent any backfeed from the towed vehicle going up to the RV. Typically this is used on the running light circuit where the power from the towed vehicle will backfeed up into the RV. Now we're actually going to use it for a little bit different application. In this situation, our Jeep has a after-market supplemental braking system installed and it provides backfeed in that fashion. We need to install two diodes to prevent backfeed going up to the RV and we'll show you the problem at the front of our Jeep here. With our Jeep in tow mode running behind the RV, we'll go ahead and check with the brake pedal being pushed down. more
