Need Help With GP Tach

[Randy_W]

It appears you are in the right hole but for giggles connect the other two with a paper clip or something and try it, could have been different or diagrams can be wrong. But even if it's right, it could just read high, not unusual for a factory tach.

Because they just aren't that accurate. I've even compared several stock GP tachs and none registered the same.

Alright so I have it hooked up correctly its just the tach is not accurate. Thanks for all the help and the pic!

I would try the other two just to satisfy myself, but it probably is just off.
