Boostcontrol ??? or Coolant?

No one seems to answer alot of my posts, would be very thankful if these can be answered.
 
do you have your knock sensor plugged in? the one you said coming from the starter area could be that

how long is the one coming from under the fuse box?
the other one looks like coolant
 
Knock Sensor is pluged in.

Imma say its 02 sensor like i thought.. I have a 1g 02 sensor on so of coarse i cant plug it in, and dont know what a 2g 02 sensor connector looks like, however i do have a 2g 02 sensor but of coarse its missing the plug so i havent bothered to swap it yet.

As for the 3rd pic.. its not coolant or boost, i just went to my garage and took a few more pics.

As you can see the boost silonoid is to the left, and i actually checked for the over fill coolant plug and its not that. I pluged it in though and set it to the side.

I dont know what this is, or were it goes but the yellow thing was something that i some how managed to break badly and lose the broke part...

Thanks for your help though :)
And thanks iceman21221 for pming me since he cannot post here :-(
 
What about your 2nd pic, it look like it would go into the MAF....or at least awful damn close where you are holding it...50/50 shot just trying to help
 
When you say second pic, you talking about from my first post or second post with pics? but i really dont think so. Thought the maf had only one plug going to it? if so its already plugged in.
 
yeah there is only one, and it was your 2nd pic from the 1st post.....m car is all tore apart so come I will go outside now and take a look...wireless net is great, hell its 230 in the morning I have nothing else going on,LOL. give me a minute and I will see if I can help more
 
ha ha, yes it is, i actually gotta be up at 7 and its 2:30 now LOL, but im actually getting replies and would love to know what it is. :thumb:
 
well you have all 3 that go beneath the thermostat right? and the one that goes to the MAF, what about the one that plugs on top of the transmission, and side not its 50deg out here and I am southern this shit is cold
 
i think i found the one from your 1st pic on the 1st post it goes to another plug of bundled wires that goes behind the head underneath the intake manifold, not sure what that is however. that bundle of wires splits in 2 one towards the tranny and the other goes behind the intake mani
 
oh the one you crushed plugs into your radiator fan, see my car is 2/3rds put together so it takes a few to figure outh what I am looking at. 3rd pic 1st post

I have piss for blood so i am back inside, let me know ASAP if I got any of these right
 
This is the one i think that goes to the 02 sensor

This is that missing, busted to hell sensor plug

its just like a cover for that yellow thing to go into... and it by the boost silnoid... nothing inside i felt around in it.

it dont look broke, and it kinda just slides into that cover thing... thats gonna be my guess

no but i have 2 left, and i know those go to the radiator. you wouldnt happen to be able to share a picture or tell me if the connector from the 02 sensor looks like the one that im thinking it goes too would you? And do u know if what im thinking is correct about that yellow thing just going into that caseing next to the boost silinoid?

YESSSSSS. The yellow sensor thing just plugs into that black cover by the bcs. I can't remember what it is but I know exactly what you are talking about and that is where it goes. Mine used to fall out all the time I had to throw some electric tape on it to keep it in.
 
sorry i don't, mine is gone, I have yet to go get a new one, I am the process of an engine rebuild, hope I have helped clear up a few things, oh PM sent
 
the yellow casing does in fact look like it goes into the boost solenoid. Also it looks like you have both the 02 sensor plug that goes to the 02 sensor and the plug that goes to the ecu. The square plug goes to the ecu and the circular plug goes to the 1g o2 sensor.
 
THANK GOD, what a releif, as long as it didnt get busted! hope it isnt something cruical, anyway the only thing i need to get verified is the 02 plug with that orange plug in Post #12 Picture #1

Hopeing thats were it goes, if so im just gonna either buy a plug or hardwire it in.

I dont have the right 02 sensor on... i have the 1g one on and havent swapped the 2g 02 sensor in yet, however... i dont have a square plug on the 2g 02 sensor either, friend i got it from gave me it with it torn off, so its just the sensor with the wires.. and the 1g has the end but is useless to me since it wrong...

im so confused on were that orange plug goes!!!
 
the square plug is for the front o2 sensor. I'm almost 100% sure, I can check it out tomorrow morning though. The problem is that you have a 1g o2 sensor that has a different plug than the 2g o2 sensor.
 
so post 12 pic 1 is infact were the 02 sensor would plug in if it where a 2g 02 sensor?
 
The square plug is either the front o2 or the cruise control, I am 99% sure it is the front o2, be careful though because the plug will fit the cruise control or the front o2.
 
will anyone take a picture of the 02 sensor connector? thanks. like i said b4 i dont know what it looks like, but my guess is it does in fact PLUG in to that orange plug if it was a 2G 02 SENSOR!
 
Wow you're having similar problems to what I had...I was going to say that your plug is probably the one that used to be mounted to the bracket on the bottom of the coolant bottle alongside the BCS. But I think you already figured that out. See, yours is yellow but I think its the same as the plug in this picture right next to my BCS:

But hey, since you're having issues in the same area as me, do you have any idea what the plug in the palm of my hand is? Nobody can figure it out. I noticed it after a fmic install. And it isn't a foglight plug. Comes off that large bundle of wires that run behind the vertical frame section next to the radiator, passenger side.
