I'm telling you man, it's yellow & red

It's on the top row (if the ECU is horizontal), second set of wires, a couple in. Just touch the wires and see what happens

lol, i was test driving my 620 the other day and had the tach signal wire exposed and it grazed my leg, thought i was gunna **** myself!!!
