'87 442...Need some electrical help!

[442_olds]

I've repaired the harness in my 442, and have the rallye pack working, but have a few wires left to connect under the dash. Ever took something apart, and forgot where it went? 😳 It's been apart for awhile. Anyway, here's some pics with questions as to where they go, and what hooks into it. Maybe this will be of help to someone in the future. Yes, I have the CSM, but it doesn't show everything (or maybe I just haven't found it yet).

This comes out of the cruise control module. I have the other (yellow) wire figured out (comes from multifunction switch connector to fusebox), but can't for the life of me find where this goes. Could this be a connection for a trailer harness switch?

I believe this goes to the A/C (brown wire), but haven't found the other connector yet.

This connector comes from the LH pillar, but haven't found where it connects, either.

One last pic:

What, if anything, connects here (next to the turn signal connector (C104))? Got 4 wires running into the column. Might have something hooked up wrong.

BTW, the cluster is working, along with the instrument lights. So I did do something right! WOOHOO!

Thanks in advance for the help! I'd like to finish this as soon as possible.

EDIT: Found where the first and second connectors go...first goes to the back of the speed sensor buffer..CSM said it was white. It was black...fits right in. Second one is to the A/C switch at the back of the heater. Now to find out what the others are. Got to have a connector somewhere for the pink wire, but not sure about the other connection. Might not be used after all.

Didn't find a connection for the pink wire, but I think it is an unused circuit, perhaps for a sunroof option (much like the anti-diesel solenoid connection in the engine compartment. VIN 9 engines don't have an anti-diesel solenoid. The factory used the same harness for both VIN Y and VIN 9. As for the connections on the turn signal switch, must be for a trailer hitch, or something that is not normally used.
Good news is that the cluster is working, along with the trunk release, and so on. Still have some things to re-install inside, but I'm getting closer to starting the car for the first time.
