Switch install

Hey yall. I’m using this diode dynamics heavy duty wiring harness to connect to an after market switch I’m using. My question is which wires go to what? And do I still need to tap into a fuse for the switch? Thanks

 

This is how I did mine, I assume the Blue, White, Black is from a relay.....
Red 2 is illumination when switch is not on, most people just wire it with the other 12V switched red.
I used a dual switch, so diagram yellow (4) on the switch will be your red2. I since tap to the Tail light 12v

 

Perfect thanks. I messed it up first and the switch light was on all the time even when the truck was on but I mixed up the red and green.

 

For the "Tall" single switch:
- Green should be connected to Blue - going out to the relay (85), when relay is closed, 12v turn on the light.
- Red1 tap to a switched 12V circuit, if you only want to turn on ditch light if truck is running.
- Red2 for SW illumination at night, tap to Tail light circuit
- Black is grounding. connect to chassis ground together with the black wire from the relay harness.

 

Man I didn’t realize how careful you gotta be with those. One of the wires touched my crimping pliers and the lights started going crazy. Appreciate the help.

 

Good luck, man.
I would suggest not to wire electrical things hot (disconnect batt. neg or not turn car on), you can short out many things and casued more damage.
