Most cutouts don't need a DPDT switch - an SPDT momentary will do the job fine. If the switch is a normal automotive one it will handle the current without the need for a realy as well. Just connect the center terminal of the SPDT switch to a power source and the outer terminals to the open wire and close wire respectively. Using the SPDT center off momentary switch means you can let go of the switch and it will return to the center (off) position when you have the cutout in the position you want.

To be honest, I don't even know what you would use the other side of a double pole switch for when connecting a cutout.

WhiteBird00, I'm currently using the basic foglight switch (thread I asked you about probably 4-5 months ago) to energize a DPDT relay. When the relay engergizes, it connects power (+) to the green wire of a McCord cutout and grounds the red. When the foglight is energized, it then reverses for ground to the green and (+) to the red thereby shutting the McCord. I would recommend giving power to the cutout from a keyed source thereby avoiding ALWAYS having power to the relay. Would you agree this works? (sure hope so since I'm using it )

Oh yes, that works. The thing I was refering to is DPDT versus SPDT. Many manufacturers label the common 5-pin relay as DPDT when it really isn't. True double pole double throw has two independant power sources and two independant outputs. In other words, it controls two separate circuits. The common relay is actually SPDT - it has double throw (completes a circuit in two different directions) but only one pole (terminal 30 input power through the 87 and 87a terminals). The confusion comes from calling the coil terminals (85 and 86) the second pole when they're really just the controller for the primary circuit.

In switches, a DPDT switch has six terminals whereas an SPDT switch has only three.

Not saying you have got to do it this way, but I ran my wires up under the rear passenger seat (little 1" rubber grommet) and wired it inside the car. Then ran the wiring along the center tunnel to the switch (which I have in my dash) above the radio. Personal choice. If you keep the wiring inside the car, less likely to get damaged or wet or what ever. . .

Yeah... I ran it up throuhg the floor through the center of the rubber OEM grommet in the floor with some silicon sealer to keep it from leaking..I was wondering where to hook up the wires to the switch ..
