lexus-is2

I've been looking at the lexus tech docs but just cannot seem to find the pinout for J65 at the back of the CD changer. The only two pins I can is 9 and 10 which seem to be the AVC-LAN communication signals TX+ and TX-. But I cannot find anything on the remaining 10 pins. Does anyone have this info please? I have an AC device that plugs in there and I want to test it indoors but need to know which ones are mainly power and ACC.

Thanks.
