    look at the manual?

    I'd guess you'd be tapping the low side of the ignition coil.

      Hook up to your NOS and LED underbody lights in parallel with a 5 farad cap.

        As a guess you'll need switched power, a ground, and the tach signal from the DME. For the DME used with an M20b25 that is the wire that goes to pin 6 of the DME connector.
        The car makes it possible, but the driver makes it happen.
