Hi there, my name is Carsten and I am writing from Germany. Am driving a 71 MM van and have a problem with the wiring of the ignition switch.
I had to unplug all cables from it and being a total moron forgot to make a sketch about the connectors. Can anyone send/provide a little sketch/list which cable goes to which connector? Didn´t find anything using the search function. Thanks in advance!!

Hi, until someone comes along with a photo, this diagram will tell you which wires go to the same terminals:
viewtopic.php?f=11&t=28295
If you have a multimeter then it is easy to test which two terminals are connected when the switch is "on". A third terminal is connected with those two only when the key is in the "start" position.

Carsten ,
If it's a 3 terminal ignition switch ( ? ), the wiring diagram for a " saloon " says : -
1. To Starter Motor Colour White with Red tracer wire ( via Solenoid )
2. Two wires Colour both White wires a. goes to Ignition warning light
b. goes to the fuse box for ignition controlled components
3 Feed from Battery Colour Brown with Blue tracer
On the reverse of the switch
The feed from Battery is a single Lucar connector , the other terminals are double Lucar connectors.
A valuable resource is the Holden website
www.holden.co.uk. They sell a number of Lucas
Ignition switches. If you can correctly identify the switch and it's Manufacturer's number e.g 31973 you can
go to bottom of the page and click on the wiring diagram for " 31973 ". You will have to scroll down a number of pages until you find the one you're after.
By the way 31973 is listed as suitable for the Morris Minor. Check that your vehicle has not been modified with another type.
Good luck Bob

Hi Bob & Simmitc,
thanks a lot! I´ll check the exact number of the switch and look for the wiring, but I assume the other info provided will already do the trick!!
