Install Is easy and simple.
1st: Disconnect the battery and remove the ground wire here (10mm)
2nd: Un-clip the Evap purge Solenoid
3rd: Un-clip the 4 tabs that hold the fuse box in and lift out of the way.
4th: Remove the battery hold down bolt (10mm)
5th: Place the fuse box with the wire pointing toward the passenger side fender. Then place the bracket that is facing toward the front under the large wire loom that comes from the fuse box. Finally place the rear mounted bracket on top of the battery hold down and place the bolt through that. Give the bolt a couple of turns but don’t completely tighten.
6: Run the wire loom along with the wire that said “HOT” in to the cabin to where you would like the switches to mount at. The hot wire is to power the switches and it’s on to “Daisy Chain” the switches for power as they pull less than 1 amp. Wire up the switches accordingly to the manufacture of your switch.
7: Next take the bundle of wires and route them away from moving parts and heat. Connect the lead to the accessory you are trying to power. You will have to supply a ground for the other side of the accessory
8: Connect the Red 8 gauge wire and fuse to the positive side of the battery and then connect the small black wire to the negative side of the terminal.
9: Turn the switch on and enjoy your “Black Box”
