Nope....
I just tore the black boot off of the back of the switch and there is nothing but the 7 wires hooked to a corresponding number.
I have once or twice used a switch that I had set to, say, three positions and only burned two onto it......I switched to the position with no program on it. Instantly died. No check engine light, no start. Why yours worked, I couldn't tell you.
