LT1KENOBi

A buddy of mine has an ls1 out of a 98 camaro in his silverado and he's spraying it.... I have a left over mallory 685 from when I had my lt1... I know the ignitions are different... but is there a way to just use the window switch function from the mallory on an ls1.....???? I figured there should be b/c I thought all you needed was the rpm tach signal....

Thanks in advance..

I don't think it will work

The 685 was producing its own RPM signal for the window switch to use....it does not have a tach input
