ps temp sending unit is located on bottom of engine, off tot eh side where there is a round stmped steel plate. the plate is retained by two screws, the plate is either flat with no sendor, or it is the special plate with provision for a sendor. if you plate is flat, you'll need the sendor and the correct plate and cover plate and gaskets.
later cars often had the wires already in teh harness for use if you get the optional ceneter cousul gages. the wires if they are present shoudl terminate near the floor under the dash in teh center of the car, they run thru the tunnel many early cars did not come with these wires preinstalled so you have to add them yourself. might as well run a couple extra wires while your at it, for later use (maybe add a pressure gage, or coil volta gage, etc....)
so see if you have some extra wires in a bundle under teh dash near the floor. you might already be wired for the gages. youwill likely have to extend the factory wires as they were ment for the gage to be in the center consul, not up in the dash like your neato combo gage is.
good lcuk
Ok, so there should be wires already in the harness. the car is a 75, and that is what the gauge cluster came from. I know what plate you are talking about, and I have seen them before on a customers car, I am an engine builder. I just had to replace my speedo cable, and found the wires you are talking about, they are just behind the shifter in my car. So, all I have to do is to run a wire from there to the gauge, and then find where it is in the engine bay. That will be easy. Thank you very much for your reply. I did not think about those wires having the one wire I needed in it. The gauge still has the blue wire with red stripe that comes from the fuel gauge for 12v power. The ground wire was not there, so thank you for that bit of info to.
