Hello, my name is***** does not have a tach wire, you will need to splice into one of the coil signal wires to tach signal. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
Control wire for cylinder 1 coil is dark pink, red/white for 2, light blue for 3, just use whatever coil is easiest to access. Each spark plug has a coil directly on top of it. Let me know how it goes or if you have more questions, thanks.
