Newbie question

Hello my first post and I’m a total newbie , I got the hornblasters shocker kit, and it looks a little intimidating. I put it all together on a spare tire delete bracket . Now I have the viair relay built in its a gray box with the wires labeled, looks straight forward however there’s a wire labels trigger switch, now I’m assuming that’s the wire the goes to a keyed ignition source. Can I use a fuse tap to the fuse box or should I wire into a cigarette port. And the other question is the kit came with 2 wire toggle switch, do I tap into the keyed power wire. I’m kinda lost on what to do with the toggle switch. Any help would be great
