AbramsMFG Taurus Premium 12V Switch Box Panel - 4 ON/Off Rocker Switch with LED Light & 1 Momentary Switch Plate, 0.11 kg

What's the distance between the outer mounting holes?

Is this a box? Pictures look like an L shape.

I want to adapt to non-automotive use. Wiring diagram seems non-standard with red negative; can red be wired positive and black negative?

Do you sell one with a non lighted power switch?
