MSD Digital Window Switch Install

[03cobra5485]

alright i've got everything hooked up, and now i'm trying to hook up my window switch.. It's an MSD Digital Window Switch, i bought it used so i don't have any instructions...Does anybody know how to install this thing? All i know is where the red and black wires go, theres white, yellow, and grey that i have no clue about..any help is appreciated.

Try the MSD web page for PDF instructions. On an analog msd window sw. ,the white wire is the tach signal to the switch(- coil lead) and the yellow is your switched ground feed to your relay or solenoid.Grey wire not present on analog sw.To protect your digital switch I would use the switch to energize a relay and use the relay contact to provide the ground connection (wire) to the NOS solenoids.I guess I have assumed that you are using the sw. for NOS.
