I figure white plastic connectors are stock VW (?)

Can anyone ID the 2 shown here (behind the glove box on an early '86)?

the 4 way connector has 2 gray wires, red, and a blue wire

the 3 way connector has the green/black, green/white and black/gray

the green/black set look like they might be the rear window wiper motor..... check those colors in bentley. I recall those are the ones I used to supply 12v to my radio in my doka, no back window wiper

Any one know what the Gray/Blue/Red wires are for? I have an '82 with the dash pulled out. It looks like a previous owner cut the wire-set near the center of the dash. The wire-set runs to the passenger side, up the right side roof (and maybe to the back?). I cannot figure out what they are for after consulting Bentley. A/C perhaps? I pulled that crap out a while ago but it was already disconnected.

I believe those are the rear speaker wires

Mine is a 7-passenger van. No rear speakers. (I don't think there are rear speakers. ???) Plus, my wiring is slightly different than the one shown in the of the original post. Mine has a single gray wire, not two.

It is a T3 connector (Blue/Red/Gray). The only T3 connector in Bentley for this model is in the engine compartment. Looks original.

I believe Casey is correct. Single gray wire is the common negative for a set of rear speakers.

Perhaps the rear speakers have been removed by a PO, but it is certainly the most reasonable
explanation for this wiring in the dash behind the radio location. You might have to tell US...???

The only "radio" wiring shown in Bentley for my model is for power on fuse #3.

<shrug>

As I understand it, the radio option (also AC, among a few others) was usually installed by
the dealer here in the US as desired for each customer. As such, the wiring is in fact "original"
(correct colors & authentic VW connectors) but does not necessarily appear in the Bentley.

You'll have to do some more detective work...

I think they are wires to nowhere. This van does not appear to have had any rear speakers originally. The single gray wire is what confuses me. Plus, it is a three-wire connector, not four, which tells me they were not intended for speakers.

I will just have to give up on this one. Thanks for the replies!

Sorry, but I mentioned this already:

This IS the original wiring for original dealer-offered stock German radio options, so YES:
(despite any other more recent experience or common sense) it is very likely that the
3-wire connector is the dealer-installed, original, "common ground" rear speaker wiring.

You yourself even said the wires go up & back, which is where the original speakers would
have been - I'm just connecting the dots for you. Check out the other end(s) and let us
know what you find.

Believe me at your own peril! Wink

Factory rear speaker wiring in a van without rear speakers would in fact be wiring to no where.

The last dot to connect is where the wires end. The wires run the the most-rear passenger-side roof vent, then into the roof from there. Unless the '82 7-passenger van had rear speakers (there is no visual indication that there were), these are the wires that pull money out of my wallet.

^That is what is commonly called "factory-prep". The factory had pre-built wiring harnesses, which fit all their respective models. Those that had factory-installed options, were delivered with those options (stereo, A/C, etc.). Those that were factory-prepped, were delivered to dealers without those options, but the wiring was there for dealers to install those options if customers wanted them. Both my Vanagon and Cabriolet have dangling connectors connected to nothing... because those options were simply not installed at the factory (or dealer). Wink

Page 97.193 in the big green book, albeit for an '86, shows this stereo T3 connector. As already said, the single gray wire is a common ground for the two rear speakers and is part of the speaker balance control system on OEM radios.

Rear speaker wires, so they don’t show up on the wiring diagram. All 3 wires run through the overhead channel passenger side. The grey wire is speakers common ground, blue wire is driver’s side and red is passenger side. If you are seeing them unconnected its likely because the PO rewired the speakers to use a modern separate-grounding stereo.

They end in the structural member at the rear hatch (passenger side)
If you want, pull the welt off the hatch trim, and the tape, roll the head liner off the flange and you can reach in and find them.
with a bit of patience and some lube use these wires to pull a 4 wire set back to the front, so you can install a good set of speakers back there.
I did.... mine sound awesome Very Happy
