    Hey all,

    I’m trying to figure out how to wire my Baja Design S8 30” light bar to my Switch Pro 9100. I’m planning on using the BD wiring harness 640122 since I’d like to manually turn on/off the amber backlight function with one of 8 switches on the Switch Pro panel. Has anyone done this before?

    I’m also using a fuse block, bus bar, and terminal bar with my Switch Pro setup.

    SP9100 should have came with a booklet with a diagram showing you which of the colors of wires go to switches 1-6, its as simple as that man.

    You have 3 wires coming off of the light bar. One is ground, one is backlight 12v, and one is lightbar 12v. You will use one of the 8 switches for the backlight feature. you will use another switch to turn the lightbar on/off.

    The backlighting feature is very low draw, I have one BD light bar, a set of ditch lights, and a set of fog lights (all backlit), all running to one switch on my SwitchPros. I have that switch turning on at power on of the truck so I don't ever have to turn on or off my backlighting.

    Don't waste your money on that harness. Its essentially for the switches that you're going to need to remove anyway.

    You'll just need to use the extra waterproof connector that comes with the light bar to make a simple run of wire to your Switch Pros

    Baja designs also makes what they call an Upfitter Harness that you could use to connect the light bar to your SwitchPro. It’s just a length of wires with the correct connector for the light bar. Otherwise you’d be throwing away a large portion of their normal harness.

    I think I’m going to go this route (luckily I haven’t purchased the harness). I just finished wiring up my ditch lights and I it was pretty simple actually.

    Oh this is perfect! Would help me save some time making my own “harness”. Do you happen to have a link?

    Thanks for the walk-through! I didn’t know the backlight feature draws so little power. Im surprised you can connect multiple onto a single switch. I guess in theory it makes sense as long as you’re under the max for that switch. I may do this once I get some more BD lights.

    By the way, which set of ditch lights do you have? I didn’t know they have backlighting

    Could you wire the backlight wire to come on with the stock DRLs by tapping or adding a fuse? I’m doing the same thing S8 30” wired to switch pros. I’ll be out of switch slots but I’d like to use the DRL too since I already paid for it lol.

    Thats how mine is wired. I didn’t want to use up a switch for the backlights. I’m sure there are other ways to do it, but here’s a sketch I did when I was trying to figure it all out. The backlight draws .6 amps per 10” section, so for the 30” lightbar it’s drawing 1.8 amps. That’s enough that I decided to use a relay instead of just tapping into the factory wiring. I have a Switchpro and fuse block so making a harness was pretty simple. The AMP connector plugs into a T-harness that daveease makes for connecting raptor style grille lights. He makes them for halogen and LED lights. I’m no electrician and had zero wiring knowledge prior to doing this and it came out great. Ignore the black/white labels on my diagram. They are reversed, lol. Told you I’m not an electrician. I’m just glad nothing has caught fire yet!

    Thanks for the diagram, I will look into doing that.

    Does the Upfitter harness come with a green wire for the backlighting?

    Any guidance would be appreciated.

    So im having issues with my light bar. I am running a BD 40" as a roofrack light bar. The main light wire goes to one of the higher amp positions on my switchpros 9100. The amber backlighting was run to an add a fuse connected to the low beam headlights with an 15 amp fuse (and the 10 amp for the low beams), i also ran the led Raptor style marker lights into this circuit but have severed that wire for the time being.

    With everything connected if i have my headlights activated, the main light on the lightbar will either flicker weakly or not come on at all. When I took out the add a fuse and replaced the standard fuse, i was able to run the headlights and my lightbar together.

    I noticed that on the diagram up top there was a relay that went between the backlight and the fuse, which i do not have. The switchpros has built in relays.
