:cheesy: I'm not laughing at you...I feel your pain. Let's take this one step at a time. I assume you are using the harness supplied by ARB, correct?
Assuming that is the case, did you follow the directions for the main fused power off of the battery and to the ARB Relay? I figure this is what you did, and then you just followed your friend's "advice" and tapped the pink wire to act as the power wire for the ARB switch. Again, assuming you have the ARB harness, it draws power in the cab from a power source so it can light the lights on three separate switches (Compressor, Front Locker, Rear Locker.) The ARB directions (at least the last time I looked at them) suggest tapping into the power wire going to the 12 volt accessory outlet. That power source has no problem lighting up multiple switches without blowing a fuse.
So, assuming what you did is tap some other wire to act as the switch wire, you may just be blowing a fuse. I don't know of the top of my head what that pink wire is. Hopefully someone else can chime in. If what you did is tap that pink wire to act as the power for the ARB relay then I you need to uninstall and start over.
