It is for the O2 sensor as I remember it. The wire that I need exits the wiring harness and goes to the bracket that is bolted to the cam cover where it is connected to the wire that comes up from the O2 sensor in the exhaust system.

I posted the relevant owner's manual pages to the above thread.

Not kidding about the rain and it seems that we have a lot more on the way (thankfully as we had been on a draught for many, many years)..

Regarding the battery (or power source), I saw in Costco a small (rechargeable) battery pack that claims to be able to jump start a car a few times it looks very portable (size of a book) and I am very tempted to buy one to take on my junkyard trips as many times you cannot determine the mileage of a car or to check if an electric component works or not before removing it, someone here may have one and hopefully share their comments.

Once I needed to pull a power seat from a car at a Pick ur Part and I asked them if I can bring the battery from my car to power the seat so I can move it to get access to the bolts. They said that`s not allowed bc it`s a fire hazard I think you can smuggle a small battery in though, or you can assemble a battery pack using 8 AA batteries for instance. Or connect wires to your power tool and use its battery as a power source.

I was considering the AA battery pack but wasn't sure if it would be strong enough to run the top motor so I figured a sawzall battery might be better. Plus, it's always fun to have a sawzall in the junkyard.

And the rain has finally lifted so I'm off the junkyard....

The only one I got is the O2 connector. Both fan/aux air connectors were broken. It looked like the engine was removed (breaking those connectors) and then put back just to get rid of the car.

OK, thanks for the effort. I think I already have an alternative for the O2 censor, so hold off on sending it. I'll get back to you if I need it.
Maybe I should market the procedure I used for verifying that everything was disconnected last time I pulled an engine... passing a string all around the engine to see what it caught on.

Bank 2 is back together with new tensioner pads.
I reinstalled the spark plug tubes with new o-rings that I bought from oringsandmore (no affiliation). The spark plugs and coils are also installed.
While the engine is on the stand I am testing the vacuum system lines and components.
While doing this I noticed some interesting details about this engine. Despite being from a 2001 Boxster S, the engine serial number indicates that it was built in 2000 but it has the single row IMSB and uses the newer white plastic injectors from later engines. So an example of the mixed up things Porsche did in the change-over year of 2001. As mentioned earlier an LN IMSB has been installed.

It has been awhile since I posted, mid-winter lethargy.
I replaced all the vacuum lines with bulk lines from Porsche. They kept slipping out of the rubber elbows and "Y"s if I so much as touched them, so I ended up putting spring clips on them.



I checked that all the valves and other elements of the system worked but there was still a vacuum leak which I traced to the vacuum reservoir. I used my homemade can of compressed air to test the reservoir after getting it wet and found the leak in the bottom at the edge. The blue arrow indicates the positioning pin that goes in the mount and the red one where the leak is.



I have a second used reservoir and it had a leak in the same place vis-a-vis the pin.
I wonder if vibration passed through the mount causes it to crack here.
I think I will reseal them instead of buying a new one.

The snow is almost starting to melt so I have been shovelling it from around the Boxsters to be ready to get them mobile when snow tire season ends in less than a week. Yay!

I repaired the reservoirs by putting a bead of Seal-All around the base where the cracks were. Before the sealant set I used a vacuum pump to introduce a vacuum into the reservoir to hopefully pull the sealant into the crack. I then strengthened the sector beside the mounting pin, where the leaks were, with Sugru (I love yellow on a Boxster...). Both reservoirs now hold vacuum and may just be stronger than new ones.

I like that you attempt to fix everything that most of us would just toss and replace. Hope it`s gonna hold

Thanks, it's half because I don't have money to throw away and half because I don't like to waste things that can be fixed... and an extra half because I enjoy the challenge.
My only worry with the reservoir is that the plastic is so old it will fail somewhere else, like the fitting for the vacuum line that looks a bit fragile. But now that I know what I am doing I could remove the reservoir with the engine in the car, although it would be a big PITA.

The new RMS is installed, the old one was leaking, although not a lot.
I took the opportunity of having to remove the engine from the engine stand to test my "Low rise dolly" which is explained here.
Engine swap getting enough clearance with a Quickjack
