And if you didn't label the TPS or the CPS plug and you are putting it back together, how do you know which is which? I am fairly certain I have them correct. What is the pinout on the LH plug that I could test to see if the right one is plug in the CPS? I guess any pin going to the CPS would work wouldn't it?

It should be, but PET lists a different part number,

1990- 928 607 015 09
1991- 928 607 015 11

I can't think of what the difference would be off hand.
