Bit of a jack here, but does anyone know of a converter cable/box/thing that would allow you to direct connect your OBDII port to aux video input of an aftermarket head unit? I saw something like that installed on a G35 once, basically the guy ran a cable from the OBDII port behind the dash and into the aux port, then was able to see torque/HP/engine codes/etc. in real-time graphical displays. Pretty freakin' cool, but I can't find anything like that online.
