 |

87 westy, mostly stock. Found a couple loose wires and mods from a PO id like to understand. Rather than typing it up, I thought it would be easier to make a video. The video is in HD and will look better after Youtube finishes processing it:

Thanks in advance for any responses |

I have an earlier van so cannot answer offhand, but it may be worth your while to learn the trick to reading the wiring diagrams in the Bentley. Once you get the hang of the current track approach to documenting the harness many things will become clear.
In this case - you'll be looking for that grey/white wire.
BTW - you must have nodded off in either 7th grade health class or 8th grade shop -- as I think you have your male and female connectors confused.  |

Hah, yes. Problem is both connectors have a female and a male part... if the metal part is male than the yellow plastic part is female, and visa versa. So maybe both ends are hermaphrodite connectors?
Whatever, Im sure everyone gets the point  |

Okay, quick update.
I took a look at my buddies 87 wiring. Turns out hes got the exact same grey/white connector that goes nowhere. Maybe thats just how it was from the factory?
However, I could not find the yellow wire anywhere. I search high and low but could not find a solid yellow wire with a yellow 'hermaphrodite' type connector on it, plugged in or not.
Any ideas? |

In my experience, the yellow wire on a car stereo is usually the constant hot, for the clock and station memory, so if you have a test-light or meter you could check that. Or simply unplug it and see if the stereo loses it's mind.

That's true for the stereo, yellow wire to battery and red wire to a switched power source. For Vanagon ignition switches without an ACC position the red wire goes to the ON position. However I'm not sure if the Vanagon fuse panel is wired for a yellow wire to the radio. I don't have my Bentley at hand, but I know the radio wiring is near the end of the wiring section and the color of the unswitched power to the radio will be indicated. The Bentley and the Owner's Manual will also have the fuse position for the radio.

| This may be a dumb question, but where does one learn how to read the wiring diagrams in the Bentley? I'm finding very hard to be able to use the Bentley at all, and I was a part electrical engineering major for a couple years back in college! |

There is a grey-white wire in late models that ran from under the cluster to the black box in the engine bay that is not used. It was originally for a check engine light, but that was never implemented by VW. Handy wire to use for oil pressure gauge, check engine light, etc.

Awesome! Thanks for the tip. I've been contemplating how to run a kill switch and I think you just gave me an idea... |

another source:
http://www.thesamba.com/vw/archives/info/wiring/Un...l_2003.pdf
and the Bentley:
The Bentley doesn't have a "how to read tutorial", but it does have the complete Vanagon systems. It is a bit of a job to find out which pages are applicable to your vehicle. If you work at it, with enough time and rereading, it will, little by little, start to make some sense.
