cool - nice to be able to check though.  glad I could help there...

yes, that's the best narness to use.  simpler, shorter, etc.

do you mean some of the harness you have does not agreee wiht the
Bentley colors?

but at some point you can tell where wires "leave" the harness, right?
And identify their function based on where they keep going to?

I would draw out the entire harness neatly on some paper or in a
computer program until every wire was exactly defined.  It's the best
way to do these custom harness jobs.  A lot of work, but worth it.

Of course, if some wires do not match the Bentley it gets tougher.
Remember there are some stupid AC functions (raised idle, EG) involved
that make things look messier than they need to be.

I don't think anyone has btdt yet, Ben.  The only two 2.3 into type 85
swaps I know of used the CIS-E to run them, which it will do fine as
long as the motors aren't all carboned up like the one in my 90Q, heh.

I did something similar when I put CIS-E into my previously CIS 82 coupe
- and did what I described above with the harness wiring.  Slowly.  But
that is from simplest harness to next simplest.  from about 2 to 3 on a
scale of 1 to 10 for complexity.  You're going from 3 to 4 or 5.  Pity
the suckers swapping in MC harnesses - that's around a 7 or 8!
