Wire location?
Alright 88 s4 turbo. The temp sensor on the t-stat neck. Mine is there trouble is the wire broke and I want to reconnect it and I don't know where it's supposed to go to. Pics would be awesome.

The stock boost sensor goes to a fitting on the ACV valve. The stock BOV goes to a fitting on the flange on the upper intake manifold that mates with the lower intake manifold - this fitting is hard to see, cause it's under the stock BAC valve. If you blocked off your ACV, then you just lost one of the fittings. -Ted |

Nothing is blocked on mine, its all there, so what fan exactly does this go to? Still unfamiliar with all the extra crap on turbo cars, im used to n/a lol, and thanks for the pics guys! So what exactly does the acv do? could i theoretically cap off the vac lines on and to it, unplug it and use it as the block off plate, cause i dont have an air pump as of right now.

Just for you, I went out in the cold to take this picture :P
I have my BOV, boost gauge, and MAP sensor all tied to that one nipple on the UIM. Works great. Just MAKE DAMN SURE you have a restrictor pill before the MAP sensor, and it wouldn't be a bad idea to have one before the BOV. One for the boost gauge isn't NEEDED, but you can do that, too. Just in case I would recommend a separate pill for each thing, using the stock restrictor pill for the MAP sensor, as that was its original intent. I stuck a piece of a vacuum connector in the line for my BOV, and I don't remember if I used one for my boost gauge. Doesn't hurt anything either way with the gauge. Damn, now my hands smell like rubber.

Oh crap I forgot you wanted the wire, too... Look for a loose wire under the IC somewhere, you might have to pull it off. There's a wire loom running behind the alt for all sorts of stuff like that temp sensor, the alternator, solenoids... If you have part of the wire on the plug end you can match it, and hopefully there aren't too many loose wires floating around. If there are you have other issues you need to address.

You could make your own blockoff plate if you want to be cheap about it. I'd just remove the ACV if you don't plan on reinstalling the air pump because I think it exists only to direct the air pump's output. It was also one of the very first things I pulled off my car because I didn't want/need it and I don't recall all the details.

Okay since I'm lacking an air pump and don't have any metal at the moment to make a plate, if I just unplug the power to the acv but leave all the vac lines on it will the pressure sensor still get a correct reading? Not gonna leave it like that just temp till next paycheck or I get a hold of another street sign for scrap metal lol

I would use a different vac nipple for the MAP sensor that you know gets the true after TB reading. But then that nipple on the ACV might do just that. There might be a hole that goes straight from the UIM through the ACV to the nipple. You could check for that by pulling it off and inspecting.

And i just found this lol, its the wires to the acv, it was all wrapped in electric tape. |

OMG someone killed it with FIRE! If that were my car this would encourage me to remove the ACV altogether.
