I wanted to get it as far away from the heat of the engine and engine compartment so I found a couple of unused firewall plugs at the bulkhead wiring block, ran the wires inside of the wiring harness, then through the bulkhead and mounted the box under the dash on the inside.

If you look at the bulkhead junction block behind that mess of A/C stuff you can just see the red wire. And that's a Holley under the stock unsilenced air filter cover and sitting on top of an Edelbrock aluminum intake with everything (Edelbrock) ground off for "stock appearing"
