Tach needs 12v, a ground and a sender wire from the regulator. Reset the pole setting on the tach. The speedo needs no voltage except for the light it works off of water pressure at a port on the lower unit or a mounted peeto on the transom. These Yamahas start better if you pump the bulb up real firm. I have had to adjust the solenoid that closes the choke butterfly`s. You have to remove the air silencer so you can see the choke butterfly`s, hit the choke to see if they are closing all of the way. Adjust as needed.
