CarDAQ-Plus is great, but price-wise...

I checked the wiring diagram in TIS and it looks like all info I need goes through mscan (though radio unit has also direct link to info display in parallel to communication through mscan). So I guess on this stage I'll have to decide on some ELM327-based scanner or Mongoose GM as a unit to start with.

I'm not sure that I undestood this:

And after all that why invest the effort in writing software for the serial port when you could just use a PassThru driver DLL? Some guy has a fairly useful MsgMon utility that helps to reverse engineer CAN traffic. DrewTech has a free J2534-1 utility posted that lets you interact with the network. With all those resources you could probably get started on the real hacking a lot more quickly.

cause I'm actually real noob in programming (probably will need someone to do this part of stuff for me)

I just wonder if getting some OBD-II scanner and wiring it to mscan pins in diagnostic lead to try to connect at lower speed is worth doing or I can damage the car electronics by doing this (I understand that Mongoose GM will work if connected to mscan leads, however the rewiring part would still be necessary since its original connector connects to hscan pins)?
