Those gauges are fairly less involved to hook-up to the car.
There is a more consoladated gauge you can have, with less electrical wires, for slightly more then 3 Auto-Meter gauges.
Volt gauge can hooked up to any electrical source.
Water Temp gauge, you will need an aftermarket inline tube to hook up to your radiator hose, (that would be the easiest way for me).
Oil Pressure gauge; you need to figure out some pipe fittings to screw on the side of your oil filter adapter housing, you might want to keep you origial Oil Pressure Switch.
The light sources is number 27 on the drivers side fuse in the car, beside the knee bolster. You can hook the the ground to the bolt on the same.
