Tail Light Isolating Diode System with Wiring Harness

Hopkins Tow Bars - 38955

Allows motorhome or R.V. to power the lights on the towed vehicle without power feedback.

• Includes 4-pole flat trailer connector.
• Wire lead: 35' long.
• White ground wire measures 42" long.

Please note - 3 wire system on towed vehicle: If the towing vehicle has a 3 wire system, where the brake signal is sent along a separate wire from the turn signals, then a wiring converter (118158) and 2 additional diodes are needed to retain separate amber turn signals. If you only use this diode kit (38955), then the vehicle brake lights will function as brake and turn lights.
