Hi Casper. I hooked many a tach to HEI. Take the + wire from the coil and attach it to the tach connection and have someone watch the Tach. Dash tachs are made to read the resistance to give You the RPMs. After market tachs need different wires for the number of cylinders it is used on. Better ignition with the HEI. NICK L72|
