Stopped to get an Equus tach today. I was reading on an A-Body forum that hooking the tach lead to the coil negative can make the tach jumpy due to possible RF interference. The answer is to hook the tach lead into the grey wire on the distributor instead, and run the positive for the tach straight to battery. Can anyone confirm this or offer their setup tips? I wil say that my coil is on the passenger side, under the washer fluid bottle. Going to the dizzy would be a shorter run.
