by that are you referring to the 4 wire connector that goes from the pickup to the ignitors?OK. My Chine-Glish is working a little better now. It looks like the instructions say to connect the black/yellow wire to your ignition trigger source. It might not like a high-voltage connection at the coil, as Phreak has mentioned above. The only other option is one of the pulse coils from the crankshaft. Which wire that might be is what you have to figure out.
