www.vintagebus.com has a nice collection of wiring diagrams, look though some of the alternate year or market ones to see what it could be.

its a super not a bus. but thanks. and looking through the other wiring diagrams i found that the 72 type 4/411 has a brw/blue wire that goes to 31 which is ground. so should i ground it? i couldnt find 2 though. i only saw the one brw/blue wire.

xSUPER72 -

Does your wire have the color stripe like the brown and blue one in the photograph below?

yes thats the wire, but theres another one that comes from the ignition key harness. and seems a bit smaller gauge

I thought the same when I was first shown the site, but believe me, there are bug diagrams on there too! :wink:
I've just looked and found several for 1971, '72 and '73 Beetles and supers - perhaps your car has a loom for a test socket from '71? Or a supplement that is not on the standard diagram?

i was replying to the other guy sorry haha. but vintage bus is where i found the type 4 schematic with the wire from the steering column. i looked at all the late model bug schematics with no success. so i looked at the ghia, type 3, and type 4 ones. and found that. i cant link the schematic so if you go to vintagebus and go under 72 type 4 youll find what im talking about :D

I believe it is the idiot buzzer wire. Since they are so annoying most have had the buzzer (squeaker) removed.

ahh yes that makes sense. that is long gone now though. what should i do with the wire? right now i have a piece of electrical tape on the spade connector, is that fine?

If you intend to install a radio in that car, the blue and brown wire (from the ignition switch) is your friend! It can be used to ground a relay to operate your radio as long as the key is in the ignition (on or off) like this:

The gray/black goes to the driver's door swith.
I use the diode because my "key in" buzzer is still connected and working. If you don't want the buzzer, you don't need the diode.
