I bought a 5 inch tach with a water temp., oil temp, and oil pressure gauge in it as well. i have the tach all rigged up but im not sure how to do the other 3. I have the sending units for each of them but i dont know how to rig them up. Any help would be appreciated.

I believe theyre electric. Theyre a wiring harness running out of the tach with wires for each of the sending units, then the sending units themselves, however they do have threads on them so im wondering if theres a spot on the engine block that im supposed to just screw them into?
