see, me being an artist type, I don't do much electrical wiring type stuff.
now this makes sense.
so I assume the side where the wire does not go through, that is for the wire with the open end that goes to my boost guage. the other side that allows the wire to pass through clamps onto my "wire of choice" in the car, to steal power for the gauge. the metal thing cuts into the rubber and makes contact with both wires at once, so the signal jumps from one to the other, and I don't have to cut anything.
Is that how it goes?
