Atomic LS
I have an MSD Atomic LS that functions OK so far. The handheld programmer works fine. I attempted to install an aftermarket tach using the grey wire from the harness and could not get a signal to the tach. I installed an MSD 8920 tach adapter, as advised by a tech, and still could not get a signal. I was wondering if anyone else had this problem, and possibly a solution?
