Going to do some autostick trouble shooting. I know the wiring has been
hacked on, so I will look at that. I found a diagram for the wiring,
but no legend with it. If anyone could help with either a good diagram
or a legend for the one on The Samba, I'd appreciate it. I found one in
German, but I can't speak German. I can't hardly do English half the
time. Thanks!

It helps us to know what is wrong so we can tell you how to make it right!
;-)

Check the electro-magnetic solenoid in the engine compartment for power
which should come from a fuse holder by the ign coil. One for the back-up
lights and one for the solenoid and they only get power when the ignition is
on.
Grounding that solenoid comes from the gear selector and that area usually
breaks a wire and then no ground is sent when you slightly touch the
selector. There is also an adjustment of the selector too!

Or if the engine dies, or almost dies, when you touch the
selector.........that could indicate a vacuum leak but I think you are
looking for an electrical problem since you want a diagram. ;-)

Speedy will probably come to your rescue and answer your request! 8^)

Dave already spelled out the info needed :)

N7 is the solenoid valve that controls vacuum to the servo for the clutch.

S1 is the In-line fuse next to the coil.

E17 is the Neutral safety switch. It prevents starter operation unless
shift is in Neutral. Also controls the solenoid valve in Neutral.

E21 is the shifter contact; as Dave points out, this is a frequent problem.

Yeah but Speedy's info sounds so much more sophisticated, professional and
technically correct! lol

Tell us what is happening with your Beetle!!!!

Ok, i set up my newsgroup to delete all read, and didnt know it was that
way. So I lost what i had on this. doh.

anyway, its not my car, and its not at my house yet. working on it for
someone. the trans started grinding in reverse, so the lady took it to
a big chain repair place. they adjusted the linkage, wiring, and who
knows what else. charged her 500 bucks, and it still didnt work. the
quoted her 2000 for parts to fix whatever they think is wrong. I told
her I could take a look at it. Should be here on thursday for me to
work on. I'm going to start with wiring and vacuum, and see where that
takes me.

Yes, good plan.

I would experiment first; listen for the vacuum solenoid valve "click"
or the whoosh of air as the shift lever is moved slightly.
If it appears that the valve is indeed being actuated, there could be
loss of vacuum in ancient, leaky hoses or else the servo is not
adjusted to pull the clutch completely out of engagement.

Boy, I hate it when those outfits rip off the unsuspecting.
