If you dont plan on retaining your stock gauges, then the senders just plug into where your factory sensors are, water temp on your driver side lower intake and oil pressure is right underneath the oil filter. You gonna need a special socket to get the oil sender out though if you want to keep it from getting broke, they are fairly delicate. they sell the specific one at the auto parts stores, put some teflon tape around the fittings to prevent any leaking.
