Hey whatsup,
I just got my FC not too long ago.
The guy who had the car before me was working on it.
Seems like he didn't do a great job on it, so I'm putting things back together now.

Theres this little plug which I'm not sure where it goes.
The connector inside is a single male spade.
I'm not sure if the plug is even suppose to be in this location as the wiring harness is all funky.

The car is a 87 Turbo II.

Thanks in advance guys!

 

a pic would be great, but what color and where in teh engine bay is it? im thinking either o2 sensor or the water temp sensor that goes on thermostart housing

 

Freakin A this board is slow.
The pics posted in a different thread.

If it's at the back of the engine, it's probably the O2 sensor, like gergrx7 said...Look down on your exhaust manifold, just aft of the heat shield, the O2 sensor should be there. Follow the wiring (if any), & see if it has a home...

Anywhere else in the engine bay, we probably need a pic, or a damn good description of it's location...

 

Ahh, now we get pics- Yep, looks like O2...

 

hmmm... man, this wiring harness is all jacked up then.
The wiring on this is REAL short.
Theres no way it will reach down to the exhaust manifold.

 

LOL, that plug doesn't go to the exhaust area- the O2 sensor wiring plug goes to IT...And yeh, it's fun to get to...

 

oh whoops, haha
thought it was the one for the exhaust. :-P
Guess its not so bad.
Thanks again for the help!

 

sorry bud but that isnt not likely the O2 sensor. The O2 sensor on the turbo engines is on the other side by the BAC valve. At least that is the way it is on my stock TII AE

I do have that plug on my car but I would have to go out and look at where it goes. I do remember that one though.

 

The poster above is correct...If you take off the Inter Cooler (4 bolts, 2 small hoses (if you have emissions..) and two ic hoses) you will see there is another plug that is not connected. I can find a pic somewhere and post what I am talking about...

Connector is surrounded by yellow:


Hope that helps.

 

Hmmm, maybe the turbos are different, but that sure as hell looks exactly like my O2 sensor harness connector...

 

well it plugs into a connector that has a place for the connector to clip too on the back mounting bracket of the IC

I would have to take the IC off to tell you what it plugs into. something near the TB

I tried

 

Hmm.. thats the problem.
I did take off the intercooler, but didn't find the other end. :-(

 

It looks to be the same size to me as well, I mixed it up too until I noticed it was on the wrong side. I thought maybe it was a Right hand drive model for a min, but I don't know much about those either.
