I thought the A/C wiring all went along the core to drivers side and behind the battery, but I'm not sure anymore. Can anyone confirm that my vacant plugs are A/C switches?

Thanks for the effort guys, and Joe, everything on the engine harness is accounted for.
I looked at it again, and this should help a LOT if someone could look under their hood:
The two plugs both come out of the same harness that supplies the oil pressure sensors on the oil filter flange, and also the starter solenoid (two subharnesses that split over the bellhousing).
The plugs are located right where these two sub-harnesses split to go their separate ways, over the bellhousing.
I need a Mensch to follow each of the two sub-harnesses from the oil filter flange and the starter solenoid backwards to where they join, and the two white plugs should be right there in plain sight.
My question is whether they mate to each other or whether they supply something I've deleted.
I snapped a quick and awful picture so you know what's up. Each connector has one wire each that goes to the vacuum sensor connector thats resting against the clutch cable, and the other sides loop around to the connector on the transmission. I'm sure most of this is stuff you deleted from the car. Hope this helps you out, the car is coming along nicely
Let me know if need anything else, I have left everything in tact on my car so it would be good for reference.

So it appears that it is all for the upshift indicator.
I'm enjoying your progress and this build immensely. I've always wanted to take on rebuild like this and I love your approach.
THANK YOU! Armed with this information, a box of parts I found at the front door when we got home from a school field trip, and a sudden new zest for Life, I finished up the CIS and installed the battery, so here's where the engine bay is at:
Now, the exhaust won't be here till tomorrow, but honestly: did you REALLY expect me to leave the ignition switch alone when I'm SO CLOSE?
Of course not. So, a few attempts that timed out the CSV, and...
*Insert really loud engine sounds, as one might expect with an open downpipe*
It idles and revs perfectly, and overall it's mostly good news:
1) The accessory belt is rock steady throughout the RPM range, and not very tight at all
2) The simplified radiator fan circuit cycles perfectly.
3) With the instrument panel temporarily plugged in to bring the voltage regulator on line, the charging system reads 13.5 volts at the battery terminals.
4) One lifter took a while to fill up and clicked at first, but now it's quiet.
5) The oil stayed perfectly clear
6) Coolant is perfectly clear, and no foam
7) The exhaust paint smoked for a bit but looks great
8) The shifter is spot on.
There are some bugs to work out:
1) The water pump developed a brisk leak at the shaft seal while sitting in the basement . New pump needed.
2)The front water jacket, which I enjoyed installing immensely because I had the intake on already, is also leaking . I took a lot of time with it and still ufcked it up
Overall I'm really happy, and mostly just relieved that the electrical system didn't suffer any apparent ill effects after being stripped down so much *phew*
Thanks again the the plug indentifications

Congrats, Eric! Glad to see you make so much progress.
As far as the water pump goes, you had to have guessed that as soon as you said this:
That said, only a small number of problems considering the work you performed. I think you deserve a hearty pat on the back. And some cold ones.

I can't wait to hear all the "told-you-so's" when the engine craps out .
The radiator sprung a leak while I was doing those burnouts that first day, but I remember it wasn't the pump.
So while I expect all of the old parts I'm using will need replacing sooner or later, I admit I didn't expect the pump to fail immediately on first start . That seems quite the coincidence.
But now that I see the new pump was only $35 complete, I do feel like I was being stupid
OTOH I'm already $3300 just to reach first engine start, buying everything that could possibly fail would make that number much worse.
Plus I still need some big ticket items like wheels and tires, re-upholstery, and a dash. I have a lead on some used Eurosport springs, so I may start with that before shelling out for my preferred H&R/Bilsteins.
You may be dealing with a totally rotted out cooling system like Becky's car had. I flushed the coolant, and then it started rejecting things. First the water pump. Then the radiator. The oil cooler three way hose. the heater valve. the heater core. It may have had a bunch of stop-leak in it. As much as we hate it - that sh!t works!

I don't feel bad at all about money spent, my point was that if one wants to make a "new" car that won't need any work for 10 years, one would need to replace darn near everything, and the cost would be absurd for a hobby econobox.
Tim, I was thinking along the same lines. I'll bet some debris that had been floating in the coolant harmlessly for years dried out or precipitated in the pump while it was sitting in the basement, and the minute I fired the engine, the shaft or the seal got gouged.
Today I'm tidying a bit, weighing the delete pile, and installing some easy stuff like brake hoses and the K-bar. The pump is on order and I'll redo the water jacket when I redo the pump.
I had that same isht happen on Laura's Golf build, I was on a shoestring budget, so I left out some minor items and did not replace everything. Sure enough, within the first year, I had replaced just about every part that I did not replace during the rebuild, and my nice clean engine had tons of oil, coolant, etc.. all over it. Lesson learned I suppose.

Replacing everything over a year's time feels better cuz you don't notice the nickles and dimes pissing away
Today I weighed the delete pile: 131 pounds! Basically I can carry someone around and have no performance penalty, except all you beer sluggers on this forum, for you I'd have to remove the hood and hatch too
I installed the new brake hoses that arrived yesterday:
I primed and painted the metal fittings, and covered them with Cosmoline once installed, to try to keep them from rusting as bad as the originals.
Then I cleaned up, painted, and installed the K-bar:
I also pulled the wires up the C-pillar for the hatch:
All that's left is the 12V+ to the license lights and to the defog element, the grounds I'll add later.
Then Petra and I went out for our Thursday Sushi lunch, hoping the exhaust would be waiting for me when we got home.
As always, fitment is adequate and the sound is stellar There was a hissing leak at the stump of the sniffer pipe (I had just cut it and flattened it), but a quick weld and all's well.
The tach, speedo, fuel gauge, and charging light all work as they should.
The oil warning was doing the 2000rpm+ buzzing/blinking thing until I grounded the white oil pressure switch (replacing it didn't work) Ideas?
Edit: I was sweeping and I have an update on the finch that got stuck fluttering around the garage ceiling and crapped on the S1 (those of frail emotion please avert your eyes):
I guess it never found the way out even though both garage doors were wide open . It must've got pooped out (pun indended) and died, which was disappointing to see.

I spent most of the day cleaning up, since the car has reached the milestone of having a running drivetrain. The tiptissery is now on the fire pit pile, and the general grunge has been removed from the garage and the basement and everything in them.
I did get the antenna installed:
I don't anticipate having a radio in this car, but:
If I want a radio someday,
I'd need an antenna,
so I'd have to remove the rear of the headliner,
so I'd have to remove the quarter glass,
and the hatch seal,
and who knows what else.
So I put an antenna in now
Oh and Blooper for the day:
I was installing the steering column, but astute observers will note that it's not on the car, and the column itself is missing.
See, the splines were a snug fit into the U joint. Now, if I'd had a screwdriver on me, I'd have spread the U joint a bit...
...but all I had was a hammer.
So I hit the top of the column, and as I'm *whack* hitting, the splines are slowly engaging *smack*, and I'm recalling that I read somewhere *smash* that you shouldn't do that *pow*, but since I can't remember why *bang*, it can't be that important...
...except that now the column is 3" too short
...and won't extend because the strap the sets the length got caught in the telescoping part and it's totally jammed I have folks with bigger tools and bigger arms working on it, but we'll see how that works out...
So I get the doofus award today
Last night I got the tail lights and the license plate backing plate cleaned up and installed:
I'm missing a bunch of bulbs but the brake lights and the reverse lights work, which is good because it means my wiring is so-far-so-good.
I also got the front end halves torn down, not much to start with that's good:
I'll think these rotors are good for one more resurfacing :
This morning we got up early to spend the day with our 10 year old's friend at the drag strip. His Dad made him this mini dragster :
He also fixed the steering column for me. The telescoping section is really snug, but to be sure that vibration wouldn't let it lengthen and bind the U-joints, it even has a nice strap rigged up to replace the one I broke, and the lower bearing is tweaked to work and slide like it should but not fall out .
It feels really smooth . Next was the switch assembly, steering wheel and column covers:
The wipers work but the washer doesn't. I also noticed the vents don't work well, so a couple of things to troubleshoot yet. I also have to get some bulbs to check turn signals, lighting, etc...

Excellent work this has.been fun to watch

BUY MY PARTS MKII MOSTLY
Those wire colors look like Green w/ White Stripe
Orange w/ ('I can't tell from here') &
Brown as in Ground Wires.
can you twist the thing around some more and snap a second picture to contrast/compare?
(I think I have a PDF version of Scirocco MkII/16V schematics around somewheres...)
Two thoughts come to mind; are the brown wires Zero ohms to Chassis Ground? (vs being brown ground wires that are switched ground wires.)
Secondly; many early VWs like ours had test point junctions for the Bosch Certified Stations/Dealers, etc to plug tsting equiptment into the loom without disconnection stuff. Theres connectors cause a great deal of head scratching if you are trying to "find out were these loose wires go?"
[EDIT] I see you fired it up and got the basics of a running engine so my post might be moot at this point.
Still, It would be nice to be definitive in finding out what purposes those wires/connectors serve.
(Oh, I just remembered- they are for the optional Flux Capacitor!. well- duh...)
