its all plug and play, buy or borrow a copy of the rigging guide and follow the instructions, on the fuel guage it depends on the fuel sender in the tank.if the sender is a US standard,yamaha standard or European standard and it works all you have to do is set the dip switches in the speedometer correctly.
the FMM will come with a sender and a harness if you buy the kit, make sure the white/red wire is taped/sealed off and does not get wet.
the rigging guide has instructions on how to hook the speedo to the FMM and how to plug each wire in.
