I used the Granatelli dual window switch without a problem..
The instructions are confusing at first.
Off the solenoids there are the two positive wires that "Y" into a single brown wire, make sure this goes to a constant 12V
The window switch provides a groud to the solenoids to activate.
I got the RPM signal from the back of the guage cluster, and the hooked up the (+,-) for the switch itself from my stereo.
You should only have a total of 5 wires off the granatelli wired up.
2 - Ground signal to the solenoids (purple wire and blue wire)
1 - 12v, for the switch itself
1 - ground for the switch itself
1 - RPM input to the granatelli switch .
On the RPM input if the source is 12v or less -- ex. off the back of the cluster, you use a yellow wire (Im not too sure if its yellow or white but the instructions tell you)
if the RPM source is more than 12V ex. ignition coil use the other wire (once again the instructions specify the color of the wire.)
for 90 bucks you cant beat this device! better than a big ass box in my engine compartment, and you dont have to buy pills to change the settings, + you can activate each solenoid independently and have them shut off at whatever RPM you want ( I had mine off at 9k)
