    I’m wanting to hook up some led bumper lights to my aux panel with after market switch. There’s a wiring harness connected to the back of the blank panels. Can anyone tell me How to hook lights to the other end of that harness, is there a fuse I need to add. I’m lost any help thanks in advance

    Don’t use the harness plugged into the blank that not what it’s for. Order a switch from Cali raised they have switches to fit in the factory spots. You’ll just have to wire the harness that came with your lights to the switch.

    Show us this harness you have found. It may have switch illumination source to the switches you're going to add...maybe even fused IGN source.

    Is that lime green, red, white with black runner and blue? Would you remove it from the "cap", pic the connector also?

    That appears to be the seat heater switch plug.

    There might be wires already but it's simple enough to run your own wires. I did it for my aux reverse lights. There's a bundle that runs through the firewall to the engine compartment. I then went down tucking it up into the frame rail to the tail end.

    But yes order a switch like someone said from Cali raised or off Amazon and you will have to wire it through the back near your pedals and out through the firewalll boot to your power/lights. Fuse it close to the power source

    If I was to get s switch for this plug, I could now use a piggy back fuse to the heated seat fuse to run my halo if I’m thinking correct

    Not really. The fuse that provides power to the heating elements is always 'hot" and in the engine bay fuse box.

    Maybe run an Add-a-fuse from the ACC (Accessory) Fuse in the panel inside the cab to your switch, and then run the power from the switch out of the firewall to your lights. That way the halos would only be able to come on when the car is turned on and youve flipped the switch.

    Or keep everything in the engine bay, tap the lime green IGN wire for ON at IGN.

    Honestly, the easiest way is for $15 buy a 10-12 ft LED wiring harness on eBay or Amazon, grab your switch you want for that like $10 (preferably green to match the factory switches) and run wires thru firewall.. Wire the new switch to the 3 wires on the harness, and to the LED light bar on the other end, and tap into a switch next to the new one( for illumination of the new switch) ..easy peasy... No cutting wires except to attach the the new switch.
