Diode Dynamics SS3 wiring to OEM switch

[JohnSadler]

Quick question for those who have wired their Diode Dynamics SS3 ditch lights to the OEM switches. What did you have to do with the harness that Diode Dynamics sent so you could ground the lights to the ground wire in the switch? Am I correct in thinking that I shouldn’t have to make battery connections since the power is already provided through the switch? Also, I don’t need the relay Diode Dynamics provides do I? Thanks in advance.

You do not need the relay or any connections to the battery. The harness that Toyota left under the hood for the OEM switches has three power wires and one ground wire. All the switches use the same ground wire. Connect both grounds from your ditch lights to that one ground wire and connect both the positive wires from the ditch lights to the Aux wire of your choice. I used Aux 2 for my BD Squadrons. I used Aux 3 for the backlight in my DD SS6 fog lights.

Aux1 = Black wire
Aux2 = Green wire
Aux3 = White wire
Ground = black/white wire

Last week I wired Diode Dynamics (DD) SS2 2” with amber ditch lights to my ‘25 Trailhunter.

After snipping off the DD relay to free up the wires to the lights, I added butt connectors to those and connected each to the OEM Aux Hi pigtail, which is controlled by my Aux 1/2 dashboard switches. My little lights have backlights, so each requires its own circuit. I had to hog up two Aux switches to use our built-in power. I connected the main beam wires for both lights to the 40-amp wire of my OEM pigtail and backlight wire for both lights to the 20-amp wire.

You may be wondering, why did you use the highest amp Aux Hi pigtail on tiny ditch lights? Because I was also wiring Rigid lights to the ARB rear bumper (bought the SPV kit months ago). Had to use the rear jumper cable up front to activate rear accessory power and rear pigtail under the bumper.

I can add to what is wired to Aux Hi pigtail in the future if needed, such as a roof mounted light bar.

We decided to get a winch but use it with a hitch mount if we need it. Wife picked up the lower priced Apex winch yesterday at Harbor Freight at 35% off so it was $300, and the winch tray/hitch mount, also on markdown. I really didn’t want to get a hitch front bumper because they are so heavy and would have to change suspension which I don’t want to do at this point if I don’t have to. More importantly, we can use the hitch-mounted winch with our Subaru Outback Wilderness. We’ll keep the winch and tray in a heavy duty cargo box, probably a Husky box, which we can take with us in either vehicle. The Subaru gets stuck pretty easily, which has so far been remedied by traction boards, but now we feel like we will be better prepared for sticker situations.

I plan to buy a more powerful 12v battery and wire a power plug for the winch directly to it, which will be run to the back of the truck probably at the bumper. Need to investigate further how other folks have done this.
