Okay I have no idea what these connecters are for?
This a carburated V6 2.8 so they may have been intended for a fuel injected model I don't know :/

An '84 V-6 may have a BARO sensor (I'm not sure).

The blue one is the barometric pressure sensor. The second one is the electric choke.

Right, it did; but the MAP sensor is over on the firewall behind the brake booster, has a similar plug except not blue. The baro sensor was usually mounted on the underside of the cowl lip right above where that white tie-wrap is, at least in V8 cars, I have no clue if it was the same in a 6-cyl car as I have never even touched one that I know of. Might even be the same sensor for all I know.

Well the second one couldnt be the electric choke, as that is I beleive on the other side of the engine and plugged in allready.

As to the MAP/BARO whats the difference with them? And I gues the flash messed up the color on the first 3 wire plug that is blue not green <bad me, had it backwards before>

Anyone with a carburated V6 who could take pictures to show me where that blue plug or/and the single wire in the other pic, Please let me know!

MAP measures the pressure in the intake manifold, i.e. vacuum; baro measures the ambient pressure. Actual vacuum is the difference between the 2. This system compensates to some extent for altitude and weather changes.

That sure does look like the electric choke plug.

Well once again, if someone can find me a picture of where either connecter goes, please let me know. I have been under the hood most of the day and can fine no place to plug either into.

Oh also, checking trouble codes I only get 12 over and over...I am assuming this is just a notification that the ECM is working?
No other Error codes come up...
