The under the hood components consist of a 12 circuit fuse panel (driver's side fireawall), a cheap amplier install kit, 4 Viair relays (passenger side firewall, lots of wire (obviously), spade connectors, and those other connectors (I dont know what they're called but it's kinda like a ring connector but open on the end so you can slide it under a loose screw without having to take the screw all tbe way out).
The panel and amp indstall kit came ftom Amazon. All I used from the install kit was the heavy #4 wire and fuse to run from the battery to the fuse panel. The kit was cheaper than buying the wire/fuse on their own.
The Viair relays came from Summit Racing.
I bought some ratcheting crimpers (Amazon) that really spread up the process and made really nice crimps. Usually my crimps don't hold, but the crimps with this crimper are solid. I can get you the name and model if you want it.
