Thank guys,

Does anyone know the pin layout on the OBD connector of the car, I.E which pins are the power lines and the K1 and K2 lines?

Many thanks

Again, pin layout is mandated by ISO9141:

Pin 16 - Battery +

Pin 4 - Ground

Pin 7 - K line

What makes you think there is a K2?

On Audis, because there were so many modules in their later cars, before going with CAN, they split the modules over two K lines and put the second one where the L line would have been. (Pin 15) The L line to wake modules has not been used since about 1996 and I don't think Porsche have ever used a second K line.

Thats great, cheers, I just was not sure if there was a second K line.

I just want to check the interface I have brought is wired correctly cause it dont work right.

Do you know what the pin outs should be on the serial connector??

Many thanks

I'm sorry, this would depend on numerous factors, such as whether the interface use opto-couplers for the level conversion or something newer, whether the software utilised the conventional TD and RD lines, or some software I've seen uses CTS and RTS to transmit and receive data.
