MSD Window Switch!
Hey,
Can anyone tell me which wire you tap off of the computer on a 1996 LT4 for a MSD Window Switch to get a Rpm Signal off of? And what would be a good rpm starting point and ending point?
Thanks,
Icemanto

Do a search for Harlan shift light and you should find a link to Hutch's install in his GS and should specify the wire to tap to get the tach feed.
I myself use an MSD ignition so I feed it off the output signal on that.

Re: MSD Window Switch! (icemanto)
I will go and look at mine and tell you when i get back in town if you don't have answer by then. I think I tapped in at the green wire coming off the coil. The window switches I use are 3200 on the low side and 6200 on the high side. I have been told don't go below 3000. I also bumped the rev limiter to 6600 on my lt4.

Re: MSD Window Switch! (owensLT4)
Yes is the green wire on the coil. Trying to find the same wire on the computor harness is near impossible with out a lt4 service manual and it is definitely different from an lt1.
