i just recently got a msd window switch off ebay for my zex nitrous kit with instructions.doe any one know how to hook this up and be able to give me instructions on where to hook up the wires? thank u
I have the 8969 in my car. You can find the instruction manual on MSD Ignition's web page. You would use the one cyllinder option and connect the RPM wire to one of your coils on the NON-red wire. I put it in the glove box and wired to radio power.
Does you Zex system have the TPS switch to fire the solenoids? Because the MSD window switch can only supply enough current to switch a relay not enough for the solenoids. You may have to put in an automotive type relay to activate the ZEX TPS switch if you want to use this as your window switch. You would also need an arming switch in there somewhere.
It looks like you will need a relay between the TPS switch and the MSD window switch. Looking at the diagrams the red on the TPS is the arming switch (12V). The output of the window switch is a switched ground, the yellow wire. So this yellow wire has to control a relay to give switched 12V to the TPS switch. I would guess you would have to install and program the TPS switch first using the procedure before you install the window switch because it would seem impossible afterward.
That looks like it would work just fine. It's pin 30 not 50 for the Common terminal. This configuraiton just puts the relay before the arming switch instead of after it. It shouldn't matter either way.
