This is what I am looking at. The tach line, is that an output from the box for a shift lite or an input for the window. Cause wouldn't that be redundant to have a tach and TPS input?

from what i read, most go off of the tps for the window switch. but you have the msd box and i'm not familiar with them. maybe they use the tps for wot activation and the box for the window? i'm really not to sure but there is a stickie on ls1tech of nitrous wiring diagrams.

Its a Nitrous outlet window switch, I guess I gotta call em up sooner or later and figure out how to program it.
