Pelican used to have some wiring diagrams online, but I think not all years, and they may not still be there. I have actual hardcopy original manuals... but a digital scan is a lot easier to enlarge!
That 'Denso box won't be needed for airflow... likewise the larger box under the battery tray doesn't do much without functional AC except to add a better air fan than stock. That said, removing it will open up some air paths that would want to be rerouted to close things off properly - otherwise you'll end up with air blowing loose under the dash, of course, instead of cooling or defrosting.
One important note, however, in the removal process... the AC wiring ties in to the control wiring for the rad fans, and those two relays up there are part of the equation. So you can't safely just remove those without some corrective wiring. One part of this was to force both fans on when you switch on the AC blower fan (which is convenient when you want to prevent the car from overheating... even if the AC system is otherwise dead)...
So for now best to leave those relays in place, and some testing would be wise to ensure both fans are able to come on when the rad temp switch is shorted (to simulate on)...
The "true" '82s seem to be the ones with the squirrel cage (modern style) fresh air fan at the base of the windshield, vs. the old propeller style. Dec '81 would definitely be on the fence... mine, for comparison, is a May 81 car... |
Good to know!! Thanks Vaughan!!! I am starting to attack with the label maker everything going on back there
I found Vol 4 of the porsche workshop manual which has all the electrical stuff in it, but there is not a diagram for the windows, and after some further digging it looks like the aftermarket voltmeter got tied into the window relay somehow  https://drive.google.com/file/d/1dtG1AnPVdAcuw3I-jKsQVJzjmcT5a3n1/view?usp=sharing
Any chance you know where I can locate the window diagrams?

Power window diagram is page 97-21 of Vol 4 - might yours not be complete? It's before the MY78 diagrams.
Do you have the hardcopy or a scan? I think the scan is missing a lot of those pages...

I have a scan, working on saving for a hardcopy because those are dumb expensive
for the wiring section I have:
Central relay/fuse plate remove and install 97-5
CIS wire harness, remove and install 97-6
Current flow diagrams for 80,81,82 97-57 my 82 sections contain Part 1 through VI (start power supply ignition fuel pumps, O2 sensor system fresh air blower cooling fan, light switch concealing headlight foglights headlight parking light rear light, brake light emergency flasher turn signal backup light horn interior light, ignition starter switch rear window defogger cluster illumination brake circuit control instrument cluster, instrument center console windshield wiper)
Extra wire harness for AC 97-55
Extra wiring diagram for AC 97-7
ground points on car 97-8a
removal plug tool 97-7
and wiring diagram symbols and explanations
sorry thats a lot of reading and words, but now I'm questioning if this is complete or not because I thought it was but sounds like it is probably not. yippee

Yeah, it wasn't till I looked because of your question that I realized those were missing... drop me your email on PM, I can send a photo... maybe also the AC diagram... and if I ever get off my duff and get access to my website again I should properly scan and upload them... bigger fish to fry...

Alrighty back with some more mystery items as I have been bouncing around the car playing trace the redneck wires, and I found some more mystery connections in the engine bay. These are over near the brake mc and booster and if I had to take a guess they are for some AC components???? https://drive.google.com/drive/folders/1xZS9rCsx7XuI8MbcXlM-cTArLF7tF1Sh?usp=sharing

The wires with the cap on the end are for a diagnostic tool as I recall... the other two individual wires I recognize as being unused, but can't remember ever figuring out what they were for...

Hey guys, back with more questions than answers on how this thing runs fuel. We discovered the bushings holding together what I believe is a pump/filter and something else (pressure accumulator???) have left the chat. However, trying to compare the diagrams for the fueling system to what is underneath the car isn't exactly lining up. Here is a video: https://drive.google.com/file/d/1kL4OV7csjP_UIP4Qhi9AvsR4JCVC7z_7/view?usp=sharing

Augh, your creeper sounds like it's about to die!!!
Just some grief to welcome you back... that said - I MUCH prefer the interlocking padded foam mats, like are sold for exercise rooms etc. They take up a lot less space than a creeper, and work great when you're in a gravel lot or grassy field... and very light and portable...
Those rubber isolator mounts are easy to come by at Bel-Metric:
https://belmetric.com/search-results?BigCommerce%5Bquery%5D=vibration%20isolator
I'm thinking they're either M6 or M8 (10mm or 13mm wrench)...
Your plumbing looks pretty correct, with the apparent addition of a small pre-filter between the tank and the pump...

LOL I have def abused the creeper, she is due for some WD-40
I was actually able to find the bushings through Advanced!!! One of the few parts we can order through them if you brute force the website/app to find it, and they are an M10 https://shop.advanceautoparts.com/p/uro-parts-fuel-pump-mount-rubber-mount-with-6-mm-studs-for-pump-support-bracket-94461011500/11928162-P
I think my big hang up is when I'm staring at the plumbing and at the PET they have both the Turbo and the NA plumbing in one photo so I'm having a bit of a time playing the game of what is supposed to be here, what has been added/removed, and what is for which model XD
From what you've said and Raize, I think I have the external fuel pump (4), pressure accumulator (12), a bonus filter, and the in tank pump (1) has been removed. My dumb question is, where does the actual fuel filter (39) live?https://drive.google.com/file/d/1wvfG6qgvw2-myTCqtZLPxzXGUIsS7d9c/view?usp=sharing

The actual fuel filter is (or should be!!) up under the hood by the LF strut tower. Easy to find if you trace the fuel lines up there.

I will go hunting today and report back because I don't remember seeing one when she was in airjail, but I also didn't look super hard

uhhhhhhhhhhhhhhhhhhhh discovered a VERY broken wire that is blue and yellow on the backside of the engine close to the firewall and between the distributor and ignition coil.
What is this wire? Where does he go to? And how in tf do I remove everything to get back there and fix it? https://drive.google.com/file/d/1_up_kfw8jNX7OvQg1O_01WSY1St3tA9h/view?usp=sharing
