Re: tach help

Purple from remote control to batt on tach.

Grey from remote control to sign/send on tach.

Black from remote control to ground on tach.

If light on tach,you can connect a jump wire from another instrument(THE LIGHT PART) to the LIGHT part on your new tach.

Re: tach help

your stator on that motor has 12 poles ...... tach should have something on the back like inserted photo ..... if this marpac is the same as yours, the setting would be 5 then.

Re: tach help

I believe you will want to set it to 12 poles, so setting 5
