My 1998 V70 GLT Rebuild Project

I can't find the other end for the life of me. I would have to move the intake hose and some other hoses that I don't want to mess with.
After looking at some vacuum hose diagrams, I think that it might be the "T-Pipe PCV" hose shown in this diagram.

Which brought me to my next question. What is THIS hose for? I apologize for not marking it, but it is the fatter one just next to the plugged one.

It's insulated

T-pipe connects to the PTC but to be sure you really must trace it back to the other end. Is there an open nipple on the PTC?. That T-pipe goes back the the PITA elbow on the intake manifold.

I can't see the two pics from your most recent post, although others in the thread load fine for me. So does the vacuum diagram.

If I am not mistaken,your loose hose looks like the vacuum hose that routes from just in front of the throttle body to the CBV. If it hugs the engine along with the PCV hoses I think you have a winner.

Must be that one. I am probably going to look again.

I'll upload the pictures again in a bit. Don't know why Google Plus images won't link properly.

I replaced my purge valve today after getting the code from VOL-FCR. I finally got that to connect to Motronic 4.4. Still working on the TCM connection issue, but I'm betting on that problem being the PNP switch. This weekend I will be able to finally take apart all of the wires coming from that ECU box to check them properly. I know I've been saying I'll do that for a while, but I think this weekend will be it.
I cleared all of the codes on M44, and they did not come back after checking again, so I'll see what happens next time I get the jumper box hooked up to the car.
I plan on going to the salvage yard this weekend to pick up some seatbelts, and when I get those in is when I will continue work on the car. I'll update the thread once I get those wires taken care of.

I can bring this off topic it's my thread... take a look at this! http://www.copart.com/us/Lot/32302665?s ... 2075357736
I hate seeing these at salvage auctions. So few of these cars left, and they're disappearing.
