MGB electronic ignition on '73 MGB

[TRickster6]

Hello all,
I've checked out the archives on electronic ignition set up's for my B but have not seen my question addressed. I have a 25D dizzy and there is a single wire that appears to run from the alternator to the dizzy. Once the (protonix) electronic ignition is installed and red/black wires are connected to the coil, what do i do with the current dizzy contact wire?

Thanks in advance for your help!

There should be a double post connector on the coil. The wire coming from the alternator remains in place along with the red and black wires from the Pertronix. See pic. Ignore the orange wire (it comes from the electric fuel pump).
By the way, this is a pic of my TR6 with 22D distributor.
