Aftermarket dash lights dim opposite of stock lights

So I just installed an ARB compressor under the hood and it all works fine. I couldn't find the dimming circuit for the dash lights to tie into for the switches LED though I finally realized I can tap directly into the rheostat. Did this and it works, but it dims inversely to the rest of the dash lights...

I assume this is due to this circuit having the opposite polarity as expected. Is there something I can do here? I have basic wiring knowledge but can't even figure out what all the 5 pins are on the ARB switch.

I have a 1st gen truck, but my friend with a second gen says he had a similar problem when installing lighted switches.

The 1st gen Tacoma, and I believe also the 2nd gen Tacoma all use ground control for the dimmer. This means that you should supply power to the bulb normally, and use the ground for the light to control the brightness of the bulb. Is that how you have it connected? I just recently installed an ARB locker system in a Tacoma, so I will do my best to help.

Hokai, well I had it as the instructions said with the supplied lead attached to the dimming circuit. But I have since figured out which of the attached ground contacts on the switch is actually for the light. So I ran 12+ power to the one that was originally attached to the dimming circuit and then grounded it out on the dimming circuit. Baddabing! It all even works.

Thanks!
