I recently got one performance shop just told me to follow the instructions but no instructions or I'm being dense and not seeing it. I have the outside coil with the grey and black connections on them. Each one has a red and white cable. I have no idea how to wire it on the blaster coil four wires and only a positive and negative post.
Engine is running on shell v power and a 10° advance with a edelbrock 14x3 open air and a performer TBI. She's also got full synthetic oil hasn't burned anything it's been about a month and a half still running same oil levels and coolant. Just need to know what wires I take from the grey and black connections and how to put them on the new coil.

 

The two white wires from the harness go to the negative terminal. The two pink wires go to the positive terminal. Done.

Note that you are better off with a stock GM ignition coil.
