Ahhh - makes sense. I removed the smog pump years back.
Thanks for the information and wish me luck as I turn the key for the first time in half a decade!

Nothing to do with the smog pump. The canister is the major part to the fuel tank vent system and part throttle cruise circuit.
Yup. That plug would go down to the charcoal canister and operate the EVAP purge valve on the line from the gas tank
Are y'all sure on that? Mine has two plugs like that for ECT sensor. One is used, one isn't. Same connector as that. I'm just checking. I don't even see that sensor in the pic.

Can you post a pic shooting down from the top on your engine bay/these plugs?
I see the ECT plug in his photo. It's plugged in. A little hard to see in his pics because the red lines of the circle are on top of it
The plugs have a clocking feature that only allows them to plug into the correct harness/plug
Yes. But there's 2. One isn't used. Couldn't that be the unused one? That's exactly where it would be.
Edit: Geez.....I finally corrected all the autocorrected errors...I think! Hate cell phones!!!!

The unused one goes down to the charcoal canister.
I can take a photo on my car later to clarify, but i'm 99.9% sure the plug he's showing that is dangling in the wind is the charcoal cansiter plug

I guess I've had mine off so long I didn't remember it going to anything....lol. I just remember a few months ago a guy posted about those both plugging into the sensor and we all told him it was impossible because of the index corner. He finally posted a pic and the corner was broken off allowing it to snap in. I just remember it being unused. No need to go to any trouble for me. I was just making sure. Thanks for fixing my memory!
Here are the same two plugs on my car, although slightly rearranged from OeM location.
one to ECT (green wire) and other (red wire) to charcoal canister

I agree with the General et al. The connector goes to the purge valve solenoid. There are no wires going to the carbon canister itself. The wires control the purge valve solenoid and the vapors get sucked into the intake at part throttle cruise
