I have an 84 944 that has 2 wires that came disconnected from the back of the fuse/relay fast on tabs connections at the repair shop, I traced one BK/YE to G3 (pwr window relay coil) but still have a BK/RE that is a mystery and I can't locate it on the current flow diagrams. I have vacant tabs on both G and H. Does anyone have a wire diagram that shows the back of this panel?

Rick, I have a full set of wiring diagrams for the early cars. I looked them all over, top to bottom and the only black/red I see is the one for the horn circuit, A8. Can you tell us what's not working?
Horn works. As far as I know right now the cruise control and the after market power door locks don't work. Long story, I had a problem August last year, car would run fine for 10-15 minutes then stop so I took it to a local foreign car repair shop. They gave it back "FIXED" but power windows (down) not working and door locks now did not work. On drive home car quit like before. Disgusted after already paying $$$ I had it towed home and put it on jack stands. I would run it weekly checking for problem and found it would restart after cooling off 10-20 minutes. Changed DME relay, still same, replaced speed, position and oxygen sensors all originals with disintegrated plugs, also found an after market alarm connection clamp-on that was slightly opened. After all of this car ran perfectly except for the windows, door locks and cruise control. Then I started to look to see what the tech had done under the dash to the fuse/relay panel and found the key in /door open alarm relay broken in pieces,the lock relays hanging and hitting the clutch pedal linkage when shifting, and numerous wires hanging loose. One of the loose wires was a bk/ye fast-on female (factory original) which I traced to the PWR window relay coil which through the Pelican prints showed went to G-3, plugged in and pwr windows now work. Back to bk/re wire, it was the same type as the G-3 wire (factory original) and hanging in the same area. I know the G and H area of the fuse block have single fast-on female connectors so that is the area I was looking in.
Also the after market power door lock relay picks up when lock or unlock is pushed but locks don't move. Any ideas appreciated. Like the 83 944,SHARP is that zermatt silver? Mine is.
There is a black/red that goes from the brake light switch (unswitched sided) to the number 15 terminal on the cruise controler box. I missed it before. It looks to be power for the cruise control or tempostat. Yes the tempostat has nothing to do with the HVAC system.You can find it in the link I provided earlier under "tempostat, page 1". Thanks for the compliment. My car is actually Platinum bronze.
I don't think these cars have clutch switch for the starter. I know mine doesn't. I think the clutch switch is only on the cars with cruise control and only for the purpose of disengage the cruise control when stepping on the clutch.
You are probably right, I know it interrupts the cruise when you shift and I reread the
owners manual and it says put in neutral to start, then it says if cold 0 weather put clutch in to take the stress off of the starter/battery oops picture turned out way too big
Thanks, old pic, has antique plates now about $25, Welcome to Sunny FL, not so much, monsoons last 4 weeks. You will be couple hours north of us, still chilly in winter.
This is one of the few places I was able to find pics of the back of the relay/fuse panel showing the G and H fast-on male tabs https://newhillgarage.com/2017/01/04...ll-switch/1984 Porsche 944 fuse/relay blockA,B C D E F PLUG CONNECTIONS ACROSS TOP. G CONNECTIONS BOTTOM RIGHT WITH 1-5 R-L BOTTOM ROW 6-10 R-L ABOVE H CONNECTIONS TO THE LEFT WITH #1 VERTICAL THEN 2-4 R-L BOTTOM ROW 5-7 ABOVE R-L SO G-3 WOULD BE BOTTOM RIGHT 3 TO THE LEFT
