I don't know if this will be of any help, but this is how my Lada was and is wired up, and works fine.

That leads me to believe the "Int" connections can not be used with the Lada switch.

Yes, thank you. The Lada sw. I removed had no connection on the "Int" terminal.

Somewhat successful. Replaced Ign. sw. this morning. Car started a couple times then it wouldn't. Wiggled the connector behind new sw. and had intermittent contacts. Unplugged connector, cleaned both male and female inserts as best I could. Still had intermittent starting issues. While cranking I wiggled, pushed, pulled connector / harness and started would disengage sometimes. Separated connector and dabbed / rubbed a tiny bit of copper powder anti-sieze (all I had to try) on both sides of male prongs. Started up 12x in a row so went for a 1/2 hr ride. Also started when I got back home 4x in a row.

Now my confidence is building but I have a question. About 1/2 the time I start it, turning key all the way to the right stop, engine turns over but doesn't start until I back off the right stop, keep letting key turn to the left (counter-clockwise) and just before switch internals are about to come off contact, engine fires right up.

Is this common or do I still have a problem?

I had similar issues, and it was the white wires coming out of the Sipea ignition switch.

Replaced with a Lada, followed the diagram above and added the ignition relays to take the load off and it's been fine for the past 3 years.

The only problem I have are the pink wires going into one terminal - haven't been able to crimp them tight enough.

Thank you,
Going to revisit this today, clean connectors again, see if I can pinch the females a little ...Lol as they seem a little loose ...sorry, and try a smidge of dialectric grease I just acquired on ea. male tab.
Also need to make sure none of the individual connectors back out of plastic box as I press together. I had to pull a few of these and slightly pry up the tiny locking tab that keeps them in place.
