ESP Defeat Plasmaglow wiring

i've wired up a plasmaglow switch to my esp/bld/abs/erm cut off. The switch works in the opposite manor i want. when the switch is fully off, the system connection is interrupted, when the switch is pressed in the wire is connected. How would i make it work in the opposite way? As a result of this the switch glows when i don't want it to. I just want it to glow when i've activated the cut off.

basically i want to make the Off part of the switch the On part. and the On the Off.

3 leads on the back of the switch. ground, power in and power out.

I'd say switch you power in and out and you should be good to go.

I'm not familiar with this circuit to know if it is normally open or normally closed, but it sounds like you installed the wrong type of switch. A typical switch is normally open - meaning that it only allows power to flow through the switch when it is in the "on" position. If this is a normally closed circuit, meaning that the ESP is operable when power flows through the circuit and you want your switch to illuminate when the circuit (ESP) is defeated or turned off, you would have to purchase a normally closed switch. If this is the case, there is no way to make the switch you have work the way you want it to, you would have to buy the proper type switch.

yeah i'm afraid you guys are right. i'm kinda bummed, i light the way the switch looks when it lights up. i've tried wiring it up backwards and it works in much of the same way. the only difference being when its cutting off the ESP it doesn't light up, and when its letting power through it lights up, which is the exact opposite of what i want.

A Bosch-style 5-pin relay that is activated by the power out side of your switch would allow you to do what you are trying to do.

Pin 30 to positive (whatever you are feeding your current switch on the input side, could be switched or constant)
Pin 85 positive from your switch output
Pin 86 ground
Pin 87a output to whatever your current switch power out is going to
Pin 87 not used
