I'm looking for a wiring diagram for a 1968 beetle. Not too much to ask for but I have 6 workshop manuals that cover everything and only one has the colour guide for the wires ! Would you believe it that's my oldest and most ratty manual and it's down to it last remaining wiring diagram which doesn't do me any good whatsoever. So is there anywhere on the net where I can download the diagram I need.

A simple Google will give you this.
