Remove the spark plugs, use a spanner to turn the crankshaft until you see a piston at the top of the cylinder (top dead centre), that is the chamber about to fire so the lead from that plug should be matched to whichever lead the rotor arm inside the distributor cap is in contact with, or is about to contact. Repeat the procedure to determine the 2nd and 3rd in the firing sequence, then you can guess where the last one goes.
Number 1 plug position will be listed on the cap. Now if you know the firing order, and you know the direction the distributor is turning, you then will know plug positions as connected to the distributor cap.
