Wiring diagram for 1970 bus

[bobby67]

Restoring a German Firetruck which has had the front wiring loom removed. Its in good condition so should be ok once recommissioned

However wiring diagram downloaded from The Samba is totally different and the threads talk alot about various changes made in 1970. Can anyone assist with a copy of the correct wiring diagram please?

cheers in advance if anyone can help

I've just uploaded the below scans onto the samba's Gallery section, taken from my official VW electrical manuals.
I'll also submit them formally to the samba's main man Everett to include in the wiring diagram section in the Technical section.
As you can see they are for early Bay special versions and seem to be slanted towards ambulances but I guess a lot of the electrics was the same for firetrucks. Note the existence of the horn repeater switch (E5) and all the wires coming off it.
