1st Q. Are you only trying to hook up a headunit right now?
It'* been a while for me, but on my 01 ssei, I believe we taped into the ignition switch, everything tapped into came from steering colum. Don't remember using anything off the PIN connector, might of though. Ran all new speaker wire and everything.
As for the hum, I had some noises myself after everything was hooked back up and turned on. First I'd recomend replacing the factory grounds with some good ones, rig one right off the battery to frame and Alternator to Frame, this helped a lot for me. I also ran 3 sets of RCA'* for my setup and end up moving them around thinking it was interference, but it wasn't, even ran a set outside the car to the trunk, noise was still there.
Let me know if you need more help.
