has anyone installed a rpm window switch ( for nitrous) into a gen ! viper? if so which wire does it go to for the tach signal....any help would be great!!!!1
If you are using the MSD window switch, you do not use the tach leads. You pick up any one of the coil driver leads. On a Gen 2 is in PCM C3. Use the search function, I displayed the location/pics of an installation for a shift light, it does use the tach leads which can be picked up in C1.
