Voltmeter and fuel gauge are not engine dependent so they will work. Voltmeter just needs a positive and negative 12V connection as well as an internal light connection to the light switch. Same for fuel gauge but the "S" terminal on the gauge connects to the sender in the fuel tank. Tach connects to engine ignition system but you will need to check diagrams to see how/where. Trim is engine dependent and the sender is on the drive. If this gauge set is a replacement for existing gauges, disconnect the old, connect the new and test it. Get one gauge working before you dynamite the entire cluster. That way you know what you screwed up or did correctly in the process.
