As I continue to go through the car I am coming across a few questionable wires in the CE area. On the pics there is a crimp of a wire to a black coming off the back of the board. It then spade connects to a red and black wires going into the loom. Any ideas.

Also, on the "brain" connector there are 2 wires spliced in with no connection. They were covered in electrical tape. Also in that pic there is a female 2spade connector that is unconnected with red and white wires.

 

When I got my 87 911 the inspector found one loose wire with tape on it. Turns out it was added to accomodate a programmable chip that had been added by a previous owner. Good luck to you in finding the answer.

 

Connecting those two green wires on the brain alters the advance to enable you to run on lower ( than 87) grade gas, do not plug them together. My 84 euro has them as well. Not sure about the others.

 

That's strange. WHy the '87 octane hookup?
Also, the previously mentioned female dual spade connector with the red and white wires comes off the last connector on the lower right of the board if that helps.

 

It's a euro, and in some areas it was sold they couldn't get gas that good!

 

My '84 US has the same dual spade connector with red and white wires. It is not connected to anything, just hanging out. Not sure what it would be for. Good place to grab 12v if you need it for anything though.

 

Regarding the two red wires with black stripes:

The only pair of red/blackstripe wires that I know of on the 84 Euro panel are power distribution to the window motors, L & R.

I think the connector and both wires belong at Plug D, Terminal 1.

Check Plug D, Terminal 1 for a space that is currently empty and tell me what you find.

(BTW I have a Euro 84 Panel apart this weekend)


I need to go look at the car to answer the remaining question about the two-pronged white connector.

 

Where is a diagram for plug d terminal 1. I have been following your thread on Pelican and I am currently doing the same. Mine is luckily in a bit better shape.
How did you get the ground on the forward passenger side. I have no worries about removing and cleaning, but I can't get my hand in there to rethread the bolt. I have decided to leave it as is for now.

 

Do you know if the windows are a 2 into 1? Looks like a black wire from the CE is spliced into the red/black wires. That would make sense because I spoke with a previous owner who said he used to have window problems and got it fixed. Maybe it had been a frayed wire.

 

Yes.
D1 sends power via those black/red wires from the output side of the main window relay VI to the window operation switches, which in-turn route wires to the respective doors.

My guess is he had a relay problem and bypassed it by scabbing into clean power from a black wire.

Euro has some trick features compared to USA in the relay department, BTW.
(it uses relay position III to enable the window to operate with key off, drivers door open, in conjunction with hatch release, and I think its also on a timer) (See your Euro 84 owners manual, pg 10, doors, for the blurb about window enable)

So, you have a blank hole in D at terminal 1, where that wire pair is supposed to go, don't you?

Plugs, viewed from the passenger compartment in-situ, are labled like this:

4 8
3 7
2 6
1 5

There is no easy plug by plug diagram. You generally need the little deck of diagrams and need to triangulate between pages. I'm about 85% complete with a complete plug diagram map for Euro and 95% complete for USA.

Finally this morning I have both and 84 USA and 84 Euro side by side in the heated garage so I can reconcile the two sets of notes.

Main differences are LH-Jet w/CPS vs L-Jet; presence of antilock (white plug Y) near Z; r foglight, frt foglight function, frt extra high beams, this window thing. Kind of upsets the plug wiring a bit compared to USA.

 

We ought to send the whole deck of wiring diagrams to Langley.
They can mount the pages in the courtyard and folks can take turns trying to decipher.

Here are some of the relevant snippets:

 

Here's my best outline so far on D plug wire function.
Not sure what else I can do to help you.

The power flow after leaving D1 is pretty easy and straightforward.
Power goes into each window switch at respective terminals 3, leaves each switch at respective terminals 1.
Power flow to L & R doors, passing through terminals 1 of the 18 pin connector and going to window motors.
Power leaves the motors and loops back to the terminals marked 2 of the respective switches via terminals 2 of the door 18 pin connectors.

 

Regarding the white connector in the far right of your original picture, check to see if it leaves the CE panel at yellow plugV, terminals V5 and V6. If so, I'm almost positive its for cars with the amp option. Radio wiring diagram calls it out, I just haven't traced its far end for 100% confirmation.

Hope that helps

 

I don't have any special stereo option so you are probably correct.
thanks

 

OK

How did you solve the window situation?
