28 daytona 2 HP 500s Tach Question
 

Hey Guys any help I would appreciate it. I am on Vacation at the Jersey shore this week & I ran aground in sand bar while idling & luckily made it out but the starboard motor sucked in a ton of sand & got all clogged up & pumping no water. So I took off all the water lines & with a hose nozzle blew out all of the sand. On my boat ( 99 Eliminator Daytona cat twin HP 500's carbs ) It was a ***** to get to the far side between the side of the boat and the motor. Any way I put it all back together & everything works perfect
all but the tach. I must have pulled off the lead for the tach but I don’t know which wire it is. Can any one tell me which wire near the distributer is the tach lead or pick up? Any help will be greatly appreciated.
Dave.
