You must use the sending units that come with the gauges. The engine size would not matter as long as the senders are installed in it. The wire from the sender goes to the correct terminal on the gauge & the wire that comes on with the ignition switch goes to the pos. side of the gauge. On the voltmeter the hot wire from the switdh goes to the pos. & the neg. is grounded.
