I have that same exact chase light. I bought a plug that my passenger tail light plugs into and has tail light and brake light wires coming out the side. I wired those wires directly to that light bar. No relays. No wire for the center clear back up light. Keep in mind the brake lights on the bar only work when the engine is running for some reason.

 

I used a Baja Designs chase light but I also tapped into that harness that you posted (I have a 2018 xpt4).

I don't recall which wire was which, but I used a multimeter to see which wire had 12 volts once I turned the key on. That's the one I tapped my running lights into. Then, I checked to see which wire got 12 volts once I had brake pressed. that's the one I tapped my brake wire into. I kept the cargo/reverse light on a switch.

hope that helps

 

Cycle Worx has a fully plug and play automatic reverse light kit. Gives you a reverse light as soon as you put your RZR in reverse and 3rd brake light comes on when brakes are applied. Just contact him and he will just sell you the plug in harness,relay and bracket needed to make your chase light work.

Cycle Worx?

 

I purchased an in-line "y" adapter that plugged into the tail light harness. I wired the two outside red to my brake lights.
The center amber is wired to the running lights. That way the amber are always on when the key is on.
There are blue strobes on either side of the amber lights. These are on a separate switch but I only use them at night.
There are two clear lights between the red and the blue. I haven't wired them yet for back up lights.

hey what chase bar is this?? I can’t seem to find any with more than 8 banks.

 

Be careful with blue strobe lights . If you can change them to be solid.
The laws are different everywhere.

I run the Rear Light Bar. Got the adapter and wired it up in a day. The mount was a lot harder to build. I wanted it high enough to be seen through the dust.

 

Hey I know this thread is over 2 years old but I just purchased the same light bar and I’m having trouble with the rocker switch LEDs staying on the whole time. Also how did you guys wire the second, hand free switch?

 

I don't think its wired to be that way. It's a 3 position switch...off/on/ momentary.
In off, its off. It lights when you turn it to the on position iirc.

If you have wired switches before, it should easily be fixed to your liking but you may have to tie it into one of the existing wires.
I have the same lightbar but i took it apart and modified it. I also had to change the wiring at the switch.

It should be a simple task though

 

your switch probably has a jumper from one of the power pins to the other.

The backlight for the switch needs to be on the accessory wire from the bus bar.

 

I installed the Xprite 27" White Amber LED Emergency Traffic Advisor Strobe Warning Light Bar on my XP1K

It works great at night but it doesn't integrate with the brake or turn signal lights. What I liked about it was that all of the lights strobes to just the outside ones.
