CAN-bus project

Anyone have technical details about accessing some of these values on the canbus (specific addresses / modes / PIDs / whatever)?

My biggest wishlist stuff to get get from the CAN bus:

1) Brake Pedal Pos (for the datalogger)
2) Oil temp (to feed datalogger, also to display on dash somewhere so I can get rid of the triple-meter).
3) 7AT TCM Temp (also for datalogger + dash).

If I at least had technical details, maybe I could get RaceKeeper to consider adding support for logging them alongside my other data. It would be really cool to get the those two temps onto CAN-driven dash gauges as well, something like this: 2-1/16" Freedom CAN-BUS Oil Temp Gauge 140-300F. Auto No Warning Light From Speedhut. , but those are for late-model GM ECUs only.

I had a hint on oil temps in the past, which I lifted from elsewhere... Mode 45 (that's hex, I think, not decimal?), PID 111F (hex). I never got any results trying to use that in various ways through simple OBD-II tools like Torque, though.
