It’s not too difficult to find out with a multimeter. Finding the ground pin is easy, just connect the meter to a good earth point on the bike and use a continuity check. Similarly to find the +12V power pin, keep the meter on the earth point, and then look for the pin with +12v on it. The remaining two pins are the comms lines. CAN H & L. You won’t damage anything if these are swapped, you just won’t be able to “talk” to the bike. If this is the case then just swap them round and you’re good to go!
Vanessa, thank you so much I guess I should of used common sense! I have a multimeter so can work this out and post my findings. Can I ask how to do a continuity test? That’s the only head scratch part!
