With the LED indicator light switch, it should be wired to a switched circuit, meaning a circuit that is on when ignition switch is on and off when ignition switch is off. I am betting that it was wired to the aux power socket (cigarette lighter socket) that is hot, or on, all the time. I wired mine to the aux power socket, but I made my own cable harness and switch with no LED light, so I have no electrical drain from a LED light. If your cut out operates with the ignition off, then it is wired to a circuit that is hot all the time. You can have it rewired or change switches to a non LED DPDT,centering, center off, switch. Got mine at Radio Shack. I have a Monte so I put my switch at very front of console in the back of the depressed pocket . Easy to use, almost impossible to see.
