I just wanted to update this thread a bit and ask for help, because I am lazy...
First, if you are looking for single quantities of the above, check Octopart.com
Second, I am upgrading to the DIYautotune DIYbob with the 122pin nippondenso connector. My plan is to use one or more of the unused plugs on the 122pin side to bring in stuff like O2 sensor, extra grounds, EBC, etc. That way I don't have any odd connectors hanging under my dash. However, I need to figure out the part numbers for the extra positions.
First, we need to find the 122 position plug, and next we need to find the parts that go into it. I will look when I have time, but I'd appreciate the help of anyone watching this for the good of the group.
Update: It looks like the 122 pin connector is this: Tyco p/n 8-353015-1 which is a start on the journey.
The connectors we are looking for are
22 pin 353028-1
