You will know by looking at the one your have.

If it does have the big hole and the 2 threaded holes for the Vacuum Shutoff Switch look inside ot see if it has the Plastic Cam that operates the Vacuum Switch.

You are correct. The gasser ignition assembly does not have provisions for the vacuum shutoff. It was not needed for testing, though. Since the electrical switch is the same, the car started but did not stay running. The electrical problems seem to occur during the starting and glowing process; the engine running does not change the symptoms.

So, I started the car up today on my lunch break to get some food. The radio stayed on but the blower would not come on again in any setting. I put it in defrost mode and tried restarting the car a few times. Still no change. I thumped and jiggled the ignition and low and behold, the blower came racing on! Time for a new ignition switch. Since the steering lock sticks if I park with the wheel straight, I am just going to order the whole ignition assembly. It is only $120. I might look into a new tumbler and key matched to my VIN if I have issues with the key turning after this. I only have to jiggle the key if the steering wheel locks; all other times, the key moves fine.

I'm about 50% confident that a new switch will resolve at least one of my electrical problems.

A little more info:

This morning, I started the car and the radio would not turn on. I turned the key both ways a little with the engine running. The wipers came on, the blower got power and lost power along with the radio. The ignition switch seems to be the culprit here. Glad I have a new one on the way.

When you get the old switch out, take it apart and shoot some photos of the contacts and post them.

I just replaced my electrical switch and column lock after similar issues, not quite as bad as Eaton's.

My accessories all now work normally.

Funola, you mean the plug pin contacts or the internals of the switch?

Internal contacts.

Yeah, I plan on taking a few pics. I had to replace the ignition switch on my F250 because it was so bad that I would go over a bump and the truck would shut off. The switch literally fell into pieces when I removed it. The design, however, of that switch is vastly different than the MB switch.

Come to think of it, the ignition switch on my other SD with less miles is a lot tighter than the one I am having problems with. It makes sense now.

Here is my update. I wanted to wait a week or so to monitor for symptoms. So far, the only problem that has been fixed is the blower not coming on reliably. The ignition lock and switch are brand new.

The wiper issue and radio issue are still intermittent. I am starting to suspect that the radio is a wiring issue behind the console. The last 3 times the radio would not come on, I smacked the side of the console under the steering wheel and 2/3 times, the radio would turn on.

Looks like I can rule out the ignition switch for the last two items.
