Use fuse taps and some wire and tap your fuse box by your dead pedal. It should be fairly obvious after a few beers.

On my Pettit boost gauge install, I ran the parking light wire to the ashtray light. It works fine and the wire is completely concealed.

Yep on the nipple thing. My Defi controller had similar wiring and I wired it all into the stereo connectors except for the light. Mine needed to be wired up to the lighting so when the lights are on then the unit lit up. I used the glove compartment wiring to do this and it all works fine
