I purchased a Teleflex tach (like this one) and i am having a really hard time getting it wired up.

I have a 1998 Yamaha 40hp motor (C40LTRW) Engine Family (WYMXM069821A) with 703 controls. I found some info by searching the forums (here). I have located the green wire that runs from the controls back to the motor, but i cannot for the life of me find anywhere that the harness will plug into on the motor. I have also tried testing around with my tester, but I haven't had any luck at all finding an intermittent wire for the tach sending wire. Can anybody shed some light on what wire i need for the tach sending wire to the gauge?

Thanks in advance!!
