Check on my Wiring of the Junkyard HEI

I do not see a ground connection at the HEI mounting terminal that is designed for that. Relying on ground via the anodized heatsink, and the mount to body is iffy.

Terminal B, the one from module to coil, has about 500V peak transient, when spark happens. It is relatively close to 12V lead next to it, and ground. Getting shocked by that could stop a weak heart, or damage a pacemaker.
