I figured it was time to update this thread as I hope to get the engine back in the vehicle this weekend.
I replaced the following hoses:
The two short hoses and the cap on the rear of the engine.

I also replaced both hoses on each of the oil cooler,

and the alternator

With all of the plumbing done, it was time to move onto the electrical.
This started with the installation of eight new O2 sensors. I went with Bosch ones from Rockauto because they were inexpensive and their shipping costs to Canada were reasonable. Here they are installed with the Bosch p/ns given.

All of the upstream sensors are direct fit with the appropriate length harness and properly keyed connectors.
The four downstream ones (Bosch p/n 16136)are a little more generic with much longer harnesses and non-keyed connectors. Bosch includes the mating half of the connector with each sensor. Only one of the four had to be changed. The picture below shows the difference between the factory and the Bosch replacement connectors (harness side).

I could have taken the original factory connector off of the old sensor and transferred it to the new sensor but it has been my experience on older electrical connectors that it is much easier to remove the female sockets out of a connector than it is to remove the male pins.
Next up was the installation of the harness itself.

I went through all of the connectors and only found one that the latch on the housing was damaged on so I replaced it. I had previously replaced both throttle body and the two fuel pump connector housings as they were being held on with zip ties.
The arrangement is a little convoluted back by the O2 sensor connectors on the transmission. This is where it is key to take good before pictures so you can get all the clips and zip ties installed where they belong You can see where I had to coil up the excess harness lengths on the Bosch downstream sensors.

Also, if you plan on doing this, install the transmission control portion of the harness (with the heat shields) BEFORE you install the exhaust. It is doable with the exhaust in place but much more of a PITA.
Here is a shot of how things are looking now. I suspended the engine and tranny between one of the legs on the car lift and the engine crane. It makes it a lot easier to get some of the return hoses and piping installed when you have full access to the underside. It also makes it easier to get the subframe back in place and everything positioned correctly on the motorcycle lift to install back in the vehicle.

That is it for now. Next I have to winch the car back into the garage and get it on the lift so I can do some work in the engine bay.
