Greetings
@Kurt Holzbacher,
Following ralmo94's directions, I opened Vol 1 of the '98 GM Factory Service Manual,
went to p. 856, and there was the connector, numbered, followed by the tables with
function, wire color code, and circuit number. He shared the screen snaps of these
pages in his reply, but depending upon the size/quality of the screen you are reading
this with, the smaller print may or may not be legible.
Fortunately, Adobe has the ability to 'print' 1 or more pages to a .pdf file. Of course there
are size limits on what we can post to this forum, but I've discovered that a 2 page .pdf
file is well within the limits. (See attached.) If you open this up, you should be able to
zoom in to wherever you need and easily read the diagram that ralmo94 identified.
Once you experience how easily the .pdf page displays zoom in and out so well, you can
see how helpful it would be to have your own copy of the '98 GM manuals on a laptop
or desktop. (Bonus points for driving a big screen from your computer, takes all the
eye fatigue out of stuff like this.)
Let us know if the attached .pdf file is what you are looking for. And if you are having
trouble with a particular circuit just post it here and we'll kick it around until we can form
a common consensus on how it operates.
Best of luck!
