Lightbar wiring question

Afternoon, y'all. I recently purchased a switch-pro 9100 and am working on installing it along with a dual clear/amber light bar as well as some ditch lights.

I'm not skilled in the wiring department, but refuse to pay the $400 I was quoted for wiring these things up.

With that, I think I've found enough material on here to wire up the switch-pro itself, but need some input on the light bar.

The light bar has two functions; amber lights on the far left and right, and clear lights in the middle. The harness it comes with has two buttons to turn each section (amber or clear) independently. My question is, when I wire it up to the switch-pro, do I completely bypass the full harness or just connect it straight to the wires coming from the light bar?

AND regarding the light bar wires, I have three. Red, Blue, and Yellow/Green. My assumption is that the Red and Blue provide power to the amber lights and the clear lights. The Yellow/Green is the negative. Just not sure how to handle this. Any guidance would be greatly appreciated. Thanks!

 

I would assume the same but verify in the instruction manual. I'd use the end the light shipped with. Whatever u connected to those relays, connect to the SP.

 

I wish the light bar came with instructions!

Where I struggle is... to install it normally, you connect a red wire to the fuse panel and ground out a black wire. Additionally, the light bar on/off switch has four wires going to it. I'm struggling to figure out how to wire it properly without screwing anything up.

 

what light bar is it?

 

Should be pretty easy to figure it out. Can you straighten out that harness with the relays on it and snap a photo of how the wires are connected to the relay plugs? Also, at the 3 pin Deutsch plug, you have red, blue and yellow. On the mating plug, do the colors match? On the relay portion of the harness you have red, black, blue and white and no yellow/green so we need to figure what that turnes into at the plug. A nickle bet that it mates to a black wire.

 

Sure thing. Wrapping up work shortly and I'll upload a photo soon. Thanks!

 

OK. The pics are a bit of a $#!+ show, but I hope these help. My old light bit the dust and was fortunate to get a warranty replacement so I cracked open the on/off switch for the photos.

Please let me know if you need any other photos. I'll be glad to send them. I appreciate the help!

 

Ditch that harness and make your own. You don’t need the relays or fuses with the Switch Pro. You’ll wire the red wire on the light to one switch on the Switch Pro and the blue to another, unless you don’t want to be able to control them individually in which case you can splice them together and run them off one Switch Pro switch.

If you want you can still use that harness if it’s long enough just snip all the relays and shit off and use the rest down to the plug for the light.

For clarity- just use the part of the harness circled in red. Trash the rest.

 

OK. There are two ways to string this thing up. Janky way is cutting the black, blue and white wires from the switch. Black goes to ground bar on the SwitchPro, Blue and White each go to their own switch terminal. Coil up all of the harness and relays and zip tie it to the inner fender well. It'll work but your going to have to tear a corner off your "Man Card".

The right way to wire it, at least how I'd do it, is cut the harness with the 3-position Deutsch connector about an inch or two from where it meets that rats nest of relays. Use your multi meter to figure out which wire of the three is the ground. You can figure this out the easy way by just doing a continuity test. Plug the two Deutsch connectors together. Keep in mind that LED's only allow the flow of electrons to travel in one direction so if you test two wires and have no continuity, switch the positive and negative leads on the multimeter with the wires your testing. Two of the wires should have no continuity with each other, one wire will have continuity with both wires. That one wire is your ground, attach it to your ground bar on the SwitchPro. The other two are power feeds for white and amber. Hook those to individual switch terminals on Switch Pro. Test it using the SwitchPro. If it all works, your done. If you cut your harnesses to correct lengths and use proper crimps and protection and have it all tied neatly you can keep the "Man Card" corners intact.

 

Thank you, sir! I'll take all efforts to retain my "Man Card" LOL! I appreciate the write-up and will let you know how it goes!
