I do not believe the tach you have is compatible with your ignition system.

if you got the correct one, it should plug into the harness under the speedometer.

the PINK wire in the harness is the tach signal. it's fed from the ignition module, not the coil.

the coil connector is wired as follows:

- A (Y/BE) is - for front plug

- B (W/BK) is + for both

- C (BE/O) is - for rear plug

let me know if you need more help.

if not, please ACCEPT my answer.
