Window switch must be modified to work w/ LS1's?
 

Does anyone know where I can buy a MSD window switch that is already set up for LS1's instead of having to send it to them to modify? Someone has to sell them already mofified?

Just buy the regular window switch and cut the two looped wires coming out of the side so that the window switch is is "4 cylinder" mode.

just cut and remove those two loops and that is it? Wow I didn;t know it was that easy...I will do that tonight...thanks!

ps. How do I wire it up on the tach anyhow?

Pin # 10 (white wire on the PCM) is the tach signal input, just splice into that wire ;)
