Mercruiser Tach Loose wiring......

My 228 mercruiser's Tachometer cuts in and out (no change in engine speed etc). I have gone behind the dash and the wires seem tight.

The question is where does the tach wire go on the engine?

I will appreciate any help.

I would look at the large round connector on the main harness in the engine bay first. I think the signal comes off the alternator.
