Another Window switch question.
I have a mallory window switch that I want to use with my NX kit and I have no idea where to hook the green tach wire to or the red power wire to. Any help is appreciated.
thanks

Green tach wire will be spliced into your tachometer wiring or to the green wire out of your MSD/Crane ignition box... The red "hot" wire needs to go to a switched 12v source. Then you should have a ground which you attach to a grounding point and a secondary ground circuit that goes to the solenoids' ground wire. The window switch is a grounding circuit that will activate and deactivate the ground for the system.

What year model? The L98's with the conventional distributor has the tach right off of it; the LT1's have a signal wire off the coil I believe. Any switched 12v source will do; just something that's hot when the ignition is in the on position. I would suggest using the same source for power that you're using for your solenoids.

It is a 92 and I will be using the fuse box for the 12v source off of the switch and I would hate to have to run a wire off of the box all the way into the fuse box. Also what color will the wire be coming off of the coil? Oh and thanks for the help.

Oh also, would you know how to hook up a MSD digital 6 ignition? I have the plug in harness for the LT1, but there is one wire that I dont know where it goes. It is blue and plugs in a seperate port on the MSD box.

I just moved my tach feed off my MSD this past weekend. I put it to the white wire coming off the coil connector right where the tach filter used to be. Now my shift light and Mallory window switch work even with the MSD bypassed.

Check MSD's website for wiring schematics...They should have one for the LT series engines. I couldn't tell you off the top of my head; it's been a couple of years since I wired one into an LT based combination.
