hey all,  wondering if anyone is using MSD ignition on there cars? I have a couple questions about the wiring.  our you running a tach with your system? and do/did you need the tach modual for the tach to work properly? what system are/were you running?  I will be running the 6AL with the fire coil. Did you wire in any anti theft switch that will only turn over the motor however, won't allow the ignition to fire with out the switch engaged? and if so, what amperage of switch did you wire into the system?

thanks
