I recently bought a set of gauges for my 307 olds which is no longer hooked up to the computer. The gauge set has oil pressure, engine temp, and volts. The only one I know how to hook up is the oil pressure which I know goes to where the oil pressure sensor is on the engine. Now as far as the volts and engine temp where do they go? I think the volts may go to the alternator but not 100% sure. If anyone has a diagram or photos of how to set it up and where to go through the firewall it would be greatly appreciated! Thank you.
