Get an old Bosch condenser from AutoZone, the kind with a mounting/grounding strap. Circa 1960s vw beetle.Mount it to frame ground, connect wire to the wire going into the ht coil . It can go anywhere. Cut the wire and solder, connect it to the spade connecter going into the ht coil. Doesn't matter, as long as it's on the ignition coil wire that comes outta the stator and connects to the ht coil.
