SerII Ignition switch wiring?

[BobJones]

Hope someone can help, I'm rewiring a SERII, all diagrams I've seen only show 4 connections on the ignition switch. Mine has 5. What am I missing.

The smoke connection. :p

Sorry couldn't help it. Is this a military switch? I'm not sure what the extra is for.

Do you know the part number? Could it be a diesel ignition switch with a contact for the heater plugs?

Either way, it should be pretty easy to figure out using a continuity tester.

I have the same switch on my 1960 series II 109 sw we rebuilt the whole car which included adding a new wiring harness... I'm pretty sure that two of the 5 connectors are connected to each other. ill see if i have some pictures of it or i will look and tell you how i have mine hooked up.
