Not sure of the orientation of the socket on the PnP board, but if you take the mating connector that you will plug in to the ECU, with the latching tab at the top, then pin 1 is on the left:

Cheer Tim that's the ethernet plug in that image. It's the 6 pin 'comms' socket I am interested in per the pinout guide on the forum in order to wire in the blue tooth module. There is no numbering on the plug I am using as to which pin relates to which number.

No, that's the plug for the comms socket, not an Ethernet connector.

LOL no problem.

Have you got a cable with an RJ12 plug on? Just be aware that many modem or telephone type plugs only have the middle 4 pins populated, so you won't be able to access pin 1 if you use one of those.
