Fuel gauge needs purple (+12VDC), black(ground) and a wire from the fuel tank sender (usually pink). Tank must be grounded as well.

Tach needs purple and black, plus grey wire from stator to provise RPM signal.

Tilt gauges are pretty much useless. Install a water pressure gauge instead. Both water pressure and speedo need purple and black, plus plastic tube from nipple on water jacket or speedo pitot.

You can feed the dash tach from the 3 wires at the control box. All other dash gauges should be wired direct to the battery with a 20 or 25 amp fuse. The engine's 20 amp fuse could blow if too may electrical devices (gauges/bilge pump/lights/horn) are wired through the key switch. If that 20 amp engine fuse blows out on the lake, the engine won't start.
