Using an ARB airlocker switch to disconnect wires?

[TuffRR]

Guys
Looking for the part i need to achieve the following - i assume it exists i just don't know its name:
I have a standard air locker switch which i want to use to have a toggle on some traction control wires ie ARB switch on = disconnect diff lock detection wire and difflock light wire.
Any clues as to what i need or how this could be done? I imagine its another form of switch?

Use the power out side of the ARB switch (the one that activates the solenoid) to activate another relay that has the diff lock detect wire running through it, but use a 5 pin relay (the one with terminals 87 & 87a). One of these will be "on" unpowered. Connect diff lock detect wire through this side and when it's powered it will turn off.
