The water temp gauge may have a sensor that must be installed on the engine or perhaps it will piggy-back (use the same wires) as the engine temp sensor. The air/fuel gauge must get a signal from the Oxygen sensor, again... use the car forum so that you will find out what wires to tap into, the oxygen sensor is located in the exhaust manifold or exhaust piping of your car. These gauges require some mechanical knowledge to install. For the oil gauge, you may be able to tap into an existing oil line or the oil pan, but you should only do this if you are confident in such things. You don't want an oil leak just because you want some cool looking gauges. Good luck, not trying to be an a** but people buy gauges and think they will plug in, they won't. They are more or less custom installations.
