MSD 8969 window switch question
Hooked up my NX kit last weekend. I installed a MSD window switch and put the lead to pin 27 (same one I used for my raptor shift light). The window switch comes on and I can adjust the beginning and end point, have it set on 1 cylinder, but it is not registering any rpms. Do I have to have a tach adapter? I have talked to a buddy and he said he didn't have to use one. Appreciate any input. Thanks
