its not too bad to wire. for the temp gauge, you just cut your radiator hose and splice it back with the temp sensor from the kit.
for the tach you just hook the wire to one of your plug wires.
for the speedo you just mount the supplied bracket to one of your front wheels and mount the speed sensor to it. then hook up your ground and youre good to go.
it has engine temp, ambient air temp,tach, speedometer, clock, hour meter, stop watch, odometer, trip odometer. plus you can set the LED warning lights for overtemp and redline and program shift LED.
