Aftermarket Ignition Switch Wiring

So I had the option of a stock (used) ignition switch or an aftermarket one. I'm going to try the aftermarket one first. It's a three position with only three terminals on the back. It may have came with a wiring diagram but I've lost it already if it did.

I stuck the multimeter on it and got the following readings (I don't know the symbol for continuity so I just used = and ≠):



Key 1 is OFF
Key 2 is RUN
Key 3 is LIGHTS ONLY?

If that is right then can I assume that power goes to Terminal 1, lighting to Terminal 2 and ignition to Terminal 3?

Does anyone actually use a Lights Only position? I can't think of any reason to use it.

I use switches like that on both of my Commandos. The light position on those runs both the lights and ignition. I think that's what you'll find.

Looking at the stock harness it looks like the main power goes to 1, Ignition to 2, tail light to 3 (?) and headlights to 4(stock switch has 4 terminals).
