Lighted switch for led light bar

I just installed a 30" Cree light bar from UTV Giant on my 2015 RZR 4 1000. The light bar came with a plug n play harness and I added a lighted rocker switch that I picked up on EBay that has a blue light. The harness is already set up with the relay and fuse and has a red and black wire that I connected to the battery. The light works fine but the blue light in the switch stays on all the time even when the switch is off and the key is off. I know I probably need to some how connect this to the ignition but I’m not sure which wire to use since all of the wires in the harness are already connected to something. Also, I ordered the polaris wiring kit to connect the accessory bar in the front to the battery so I would like to wire the light to the accessory bar and and haven he blue light go off when the switch is off. Anyone know how I can accomplish this? Thanks
