i need help on finding some wires please help!

hey guys i have a 1993 f-150 extended cab short bed truck. it used to have a strait 6 5 speed in it. now it has a 3.4 cummins diesel in it along with the 5 speed. I took the motor out and sold motor with the harness. now what i do need to figure out is what wire going to the plug on the inner fender is for the oil pressure guage? also what one is for the water temp guage? cause i wanna hook up the factory gauges into the new motor. also i need to find a hot wire thats hot in the start and the on position but that wont be hard to find with a test light. the wire for oil pressure gauge and water temp gauge is the 2 i need to find. please let me know if you can help! when i sold the motor i just unhooked the wiring harness at the inner fender and let harness go with the motor. so any help is very appreciated.
