You don't need to connect wire 18. If you attach it, you will get a
small amount of mixture enrichment while starting, but this is seldom
necessary.

It wasn't a dealer installation, The '68-9 CS system came that way
from the factory on some cars. It requires a completely different FI
wiring harness and some extra parts, one of which would be REALLY
hard to install with the engine in the car. I've never been able to
figure out who got it or why. My '68 was bought in Indiana and didn't
have it. I've worked on lots of '68-9s from Wisconsin and Minnesota
and never came across one with the CS system. All I've ever seen are
bits and pieces.
Maybe North Dakota cars got it, or maybe each dealer could specify
whether they wanted their cars with it. I've never seen anything that
spelled this out. All I can find is that it's M 229.
