Help wiring window switch to Zex wet system...
I bought the summit window switch and i have a couple question's about how to wire it!
Heres the instructions that came with the unit.
1:Connect the black wire to a good groung.
2:Connect the red wire to a switched 12v source.
3:Connect the yellow wire to an rpm signal.Most likely the primary side of the ignition or to an rpm signal from the engine computer or ignition box.
4:The blue wire is ground above and below the set window,BUT NOT IN THE WINDOW.
5:The purple wire is ground IN THE WINDOW but not out of the selected area.
Ok i have the Zex wet system what do i connect the purple and blue ground's too? and where do i connect the yellow wire too for an rpm signal?
Car is a 95 z28.

you will need to get a standard 4 pin automotive relay.
pin 87 will connect to the white wire on the ZEX NMU
Pin 30 will connect to the reference wire on the TPS
Pin 86 will tap into the 12v acc wire off your master arm switch
pin 85 will connect to the purple wire
wire the window switch according to the supplied instructions....you will not use the blue wire.
this is the closest diagram I all ready had...this shows the relay in conjunction with the Zex NMU

think of the relay as a switch....the reason you have to get one, it allows the window switch to control turning the Zex NMU on and off
Most nitrous kits use one to control the solenoids...the Zex NMU has it built in. So we need to add one for the window switch to control.
