Diode Installation Instructions for a Dinghy with Separate Tail Light Wiring

This page provides detailed instructions for installing diodes on a dinghy with a separate, 3-wire tail light wiring system, providing the dinghy with operational tail lights while being towed

Tie in the left-turn circuit from the tow vehicle wiring harness using a spade connector Attach the yellow (left-turn) wire from the converter to the remaining input prong on the diode Tape up connections to secure them Running lights: Locate factory left-side running light circuit and install diode, leaving one input prong open (temporarily hold off installing the wire from the wiring harness) Next, locate factory right-side running light circuit and install diode, again leaving one input prong open Create a jumper wire to carry the running light circuit from the left-side running light to the right-side running light Cut an extra length of wire that can extend from the left-side diode to the right-side diode Twist the loose end of the jumper wire on the left side and the brown wire from the wiring harness together and insert the twisted end into the spade connector Connect both wires to the remaining prong on the right running light diode Locate factory right-side running light circuit and insert diode Run the remaining loose end of jumper wire across and attach it to remaining prong on the input side of the right running light diode Brake lights: Locate factory left-side brake light circuit and install diode, leaving one input prong open Locate factory right-side brake light circuit and install diode, leaving one input prong open Create a jumper wire to carry the brake light circuit from the left-side brake light to the right-side brake light Cut an extra length of wire that can extend from the left-side diode to the right-side diode Twist together the loose end of the jumper wire on the left side and the red wire from the converter box and insert the twisted ends into a spade connector Connect both wires in the spade connector to the remaining prong on the right brake light diode Run the loose end of jumper wire across the back of the vehicle and attach it to remaining prong on the input side of the right brake light diode Right turn: Run a length of wire from the green wire on the output side of the converter to the right-side turn signal Connect the green wire from the output side of the converter to the extension Locate the factory right-turn circuit and install diode using process outlined in the "left turn" process Attach the end of the extension coming from the green wire on the converter to the open input prong on the right-turn diode |
