Hello, I just ordered an Air Lift 1000 setup for my 2003 Yukon. I was looking over the fuse boxes today to try and find a vacant slot that is 20 amps. The interior fuse box, which is wear I'd ideally like to run the power from,seems full. In the underhood fuse box, I think I might have found a candidate. It's labeled as HID in the manual, but I'm not sure if it is powered only when the ignition is on. So basically what I need is a power source of at least 20 amps that is only under power when the key is in the run/on position. Any ideas?
