It is simpler then it seems once you get started .First get all the wiring and tubing from where you plan to mount them into the engine bay through the plug near the gas peddle in the fire wale.
Then you should have a ground and a possitive wire on each gage.You can run the grounds to a bolt on the body of the car or to the ground on the battery. For the Power wire If you dont want to have them on even when the car is off, you will have to connect them to a power source that turns off when the car is turned off. For mine I took off my steering column and used a volt ready to find the wire off the ignition that lost power when car is off. You could run power to battery and put a switch in but that is a halfed ass way to do it
Then after the power and ground is connected all you have to do is hook up the sensers and boost tubbing.
For the boost gage all you should have to do is run the vacume tube to the vacume tube b and near the bov you will need a t pvc splitter to splice it in there.

For the oil pressure the best place I found to hook up the sencor was under the top mount intercooler there is a threaded plug in the block you need to remove the plug and put in the pressure sensor. You may need an adapter because the threads in the block may not be the same as on your sensor use tephlone tap when you but the sensor in and crank it down hard so you dont get any oil leeks.

For the egt you can do one of two things. If you have an 02 sensor that come with the gauge you can take out the stock o2 and put it in there this may resolt in the check engine light coming on. You can also but a new 02 bong in somewhere in the exhaust and put the sensor in there leaving your stock o2 sensor alone and elemenating the engine lights issue Hope this helps I little and also if after you get this done and if you take out your block plug for the oil pressure sensorI am looking for a plug let me know
