Using the OEM slots works for me. The goal is install a couple front bumper lights along with a rear light now i just need to find 2-3 good quality switch's to go into those slots. My existing ARB Compressor and locker switch's are in the panel so there good were there at. I'm currently single compressor operation but looking to upgrade to dual ARB air. I wonder if if i have to run two compressor switch's (one for the locker & one for airing up) Or is there a configuration that will allow me to use my existing ARB Compressor switch to air up and use the locker.
