Need help ID'ing 3 things

I just bought my first metro (93 1.0L 5spd)
and I absolutely love it, not for the gas milage, but the price of replacement parts makes it easier to spend more time working on it.

However I see 1 vacuum hose and 2 electrical connection that I'm not sure what they used to belong to, hopefully somebody can help me out.

Green White wires look to be spliced in, not sure what it was from, just making sure its nothing stock

Behind passenger headlight, another connection, Haneys manual didn't explain any of these.

Thanks,

the fitting with the screw in it is supposed to go to a dist with vacuum advance. the plug by the distributor is for egr solenoid. it looks like someone swapped the egr manifold for a non egr one so you don't need the hose or the plug connected. it will run just fine without it. not sure what the 4 wire plug is for. do you have a 4 wire O2 sensor on the car and is it hooked up? if it is then other plug is probably for something like AC or a different option you don't have

I believe the top pic and bottom pic show the two ends of the air intake.

From what I can tell, the top pic shows the air-cleaner missing a hose that would connect to the opening on the bottom pic (air intake in front of front passenger-side wheel?).

The link below shows the hose-path:

thanks crvette69, I had a feeling it was for the egr, and the connection by the headlight is probably for the ac compressor (which I dont have) because I have a non-heated O2 sensor so theres just 1 wire going to that.

Mike_Van, I got the car without the entire intake assembly, much is missing, I should have fun ebay shopping, and digging though junkyards getting all the missing pieces

Good luck with the parts-hunting. I am trying to find interior parts for my '93 4-door, and can find lots of 2 doors, but the others seem scarce. If you come across any with good front window regulators, dash trim, etc., let me know!
