Tach signal made easy

wymoteeZ

I was having fits finding a good RPM signal for an Innovate MTX Boost/Shift gauge. This MSD GMR Pickup works perfectly. Hooked over the white/grey wire on any ignition coil. I used the one by the oil fill (cyl. #2). Set the MTX gauge to 1 cylinder/.5 pulse. All the ignition coils have a white wire with grey bands -> This is the one to put the MSD GMR on. All coils also have a black wire. The third wire varies on each coil. #1-yellow #2-green #3-blue #4-grey #5-violet #6-sky blue. The cylinder #'s from the front of engine back are 1-3-5 passenger side & 2-4-6 driver side. Hope this helps others.
