The only thing that I can tell you is that you will need the sending units for the three gauges. The oil sending unit will go up by the oil filter and the water temp will go into the intake manifold. If your car is fuel injected then you may have more than one temp sender. On a carb car the sender is in the drivers side front of the intake manifold. The oil temp I am not sure of. You will have to find a spot for it. Either using a tee at the oil pressure sensor or finding another fitting going into an oil passage or the oil pan. More than likely you will have to get some pipe fitting ada[ptors to match the thread on the senders to the engine. If there is a ground wire for the gauges and/or tach I would run that to the engine also.
