Circuit Suggestion for Tapping Fuse for Install of Air Lift WirelessONE Compressor System

Question:

Thank you for the help. In response to wiring to fuse box on a 2015 GMC Sierra 3500 duramax Denali.id like to share with you what I ended up doing. Instead of using the fuse tap supplied with the kit.. Which did not fit at all on anything..I went to my local auto supply store and purchased a fuse adapter that took the place of my regular two prong fuse. This had two places for fuses.. 1 to take care of the existing fuse. The second had a wire off it to power up a 12vdc relay I installed to draw way less amperage off the tapped fuse.these circuits are powered off the ignition switch for trailer lites...only when switch is on..the higher fused battery power is wired threw a normally open contact on relay ... Powering up air compressor.. This all works great.!!! And not having to worry about a bad connection on the fuse box.. As per wireless air instructions.. The relay is fused at 3 amps.. The battery power.. 15 amp.. Just wanted to share this set up with you..

I can only recommend you go with the same amperage rating as what is called for in the install instructions of the Air Lift WirelessONE Compressor System for Air Helper Springs # AL25980 that you are installing.

Since you want to use a circuit that only sees voltage when the key is on the radio fuse is a common one that is used. You have to go with the same voltage though as too high may cause damage to the compressor and too low would cause the fuse to blow all the time.

I attached an install video on a similar GM truck that should be helpful as well.
