Hi guys. How do you know which is pin 5 on that on the diagnosis connector (#11)? I see 4 wires: thick blue, thick white, thin white-with-blue-stripe and thin red-with-yellow-stripe. Which of those is pin 5? (Near that connector are the 2 black solitary wires with blade-like connectors, which I take to be diagnosis terminal, #12.) Thanks!
