The oil pressure sender is located on the rear plate (cast iron) to the right of the rear upper spark plug, on the drivers side. If you've got a J-spec 12a engine made prior to 1981 it won't have an oil pressure sender, just a switch to activate a light as they didn't have oil pressure gauges until '81. You can get around this by drilling/tapping a thread into the base of the oil filter stand (carefully, it's aluminium).

thanks now i know why i couldnt find it someone put a 2 inch threaded bolt in the hole instead of replacing the pressure switch. Well thats all part of buying used cars. All the fun is in finding and repairing other peoples mistakes lol
