89 Yamaha 200 wiring a new tach? Plz help

[DevonG]

Hi everyone. Just finished restoring a 90 Proline CC. Got this boat in ruins and everything was cut up. I've been reading up on tachs and the Sierra won't work with lighting coils setups and I could really use some direction on where to find the tach signal wire and an analog tach I can use. I've established that it's 12 pole and the wire might be green? Any idea where I can find it on the motor? Thankyou in advance.

From Yammies manual.....


"Electric start

The following instructions apply to a model without a tachometer installed,
or for a model with a tachometer installed, but a second meter is needed to
assist in adjustments. Inside the control box, the Green lead with the female connector is
input or signal lead. The Black lead with either a male or female end
connector is the tachometer return or ground lead.
Connect the tachometer to these two leads per the instructions with the
meter Input and ground."
