Yup. Eliminating it for an ignition conversion?

It's likely a wire in the harness somewhere.

Just ignore it. I assume your problem is that you
have 6-9V at the coil but your new ignition wants
the full 12V.
Unhook the wire that provides the 6-9V and tie
it up nicely. Attach a "proper" 12V line that
provides 12V when ignition is on. I don't have your
exact car, but there should be one around.
My Midget was wired similarily, but I removed
the ballast to install my Pertronix. Just wired
around it.
