It's always a good idea to test things before randomly replacing parts. That
can get expensive quick.

Potterman should be able to help there.  Possibly donor wiring harnesses out of
a junkyard, depending on what you need.

In my opinion, a properly running CIS-E is a very nice system.  Once you 
get experienced
with it and know how to do the tests there nothing to it.  I've done some 
work on the 90's stuff
(with OBD-II systems) and want nothing to do with it; It was a 
nightmare.  Just my opinion though.
