I want to add computer diagnostics to my in car computer system. Unfortunately my 4runner is a 95 model and as such does not have a OBDII diagnostics port- at least I do not think it does. Anyone knows how I could go about getting some info from my truck to the computer.

I do have a diagnostic port in the engine bay next to the fuse box unfortunately I know nothing about geting this to work with my computer running windows XP.
