The constant power from the battery is actually (A4- +B). Atleast thats the one I used when I did mine.

Yes A4 is the pin number. B+ stands for positive power from the battery.

I happened to have the OE diagram and the plug letters are different from the ones on that website... just had to double check before I short anything else....

I used the info on the site for my whole install and it all worked perfectly the first time I turned it on. If you have conflicting info on the OE diagram I would probably just use a tester on all the wires while the car is off to see which pin the constant power is.
