Just bought s timing light and among the many other problems I found once I lifted the bonnet, I realised I have nfi how to put the car into diag mode. I don't have one of those handy test ports next to the fuses - only relays. There's a connector at the end of a loom on the driver's side towards the back of the engine bay; do I just short top and bottom on the LHS?
