I'm ready to install a nitrous arming switch and having some trouble. On the switch I brought there is a Power, ACC, and ground. I use the ACC spot located on the fuse box for the power, found a ground, and hook up the zex brain to the acc. My question is...do I need a inline fuse somewhere?

 

yes, you should have a fuse between the power supply and the switch.

 

What size fuse would I use? Would 15 be ok?
