Msd Ignition

Has anyone actually installed an MSD distributor on a '94? I am looking to do so but need to know the wiring to get a signal for the computer. Thanks, John

Figured it out. Thanks.

If you look at your coil you will see a wire that goes from one of the coil terminals up into the wire harness that serves the air flow meter. That's the wire for the engine ecu. It needs to stay.

The other wires on the coil are power and the wire to the ignition amp. That's what you replace with your new setup.
