S4/S5 Power System Rewiring

I posted this up to a local forum; this might be interesting to you guys. I've gotten fed up with the wiring system in my S4, so I've started rewiring all of the 'important' parts as I move my battery behind my passenger seat.

I'm going to be using an Omron A22 illuminated kill-switch (like the kind you see in industrial applications), for the NHRA-required rear kill-switch, and a big-red-key-style switch for the battery disconnect. The kill-switch is going to be mounted where the license plate is, and will be covered for street use.

The alternator field is being routed directly to switched power, so that any of the kill/disconnect switches will actually stop all electricity being routed into the system.

DigiKey sells Omron's product line, and has them in stock:
