Pioneer nkp-d51

Hi all,

any ideas how to find out what the pins are for a head unit that one doesn't have the wiring diagram for? I have a Pioneer nkp-d51 out of a 2002 japanese supra, can't find a thing on the net anywhere. i do have manuals etc, but they (in all japanese) don't seem to have that information in them.

Photos of the unit can be found at: www.sretenovic.net/nkp-d51

The closest thing i've found thus far (including google's impressive japanese to english translator) is:

The diagram there shows very similar connectors, but because its very hard to read it might take someone with a little more experience and know-how than i have to decipher it.

Thanks for any help,

sorry about the link to the similar wiring diagram, its there but when you click on the translated version, you don't get the bigger version of the image. it can be found here:
