opel obd2 interface schematic

Hi,

I need any information about the diagnostic interface of OPEL car's... I need to design a clone, of Tech-2, or Tech-1 diagnostic interface, for my own purposes. Can someone help me? Any interface schematic, or PC software can help me too..
 

tech1 diagnostic

GM and Opel cars uses VPW interface. I think datasheets and links below will be useful:

Texas instruments (with TMS470) and Freescale (with HC12 series) had built in Class 2 Interface (J1850 VPW) machines into your processors. If you need some help about any OBD2 interface: J1850VPW, J1850PWM, KWP2000, ISO9141-2 and CAN, or interface in TRUCKS SAE J1587/1708, because I work with this protocols.

This protocol don't have standards and is very old, I don't have much information about this.

Will u plz help me with OBD II protocols used in Toyota corralla, Honda and suzuki cars. I have searched the net but it seems that useful free data does not exist. I will require the specification/ possible application notes of the protocols used in these systems. I will be much grateful......
