The gauge harness 6Y5-83553-N0-00 powers up gauges, connect gauge harness to key switch matching colors red, yellow, green and black and connect other end of harness to gauge.

Thanks

Ordered one, this is all i need its a four storke and a jet so the oil and trim are not need. This should give me the tech reading and hour meter correct.

Thanks again for all your help
