Figuring out which distributor terminal is No.1 is not difficult. Remove spark plug on the front No.1 cylinder. Crank engine until you feel compression on No.1. Go around a few times until you can stop the engine just as the air stops coming out of that cylinder. If you are a perfectionist, a piece of wire can be bent and put in the cylinder to exactly find top dead center, but just sensing when the compression stroke is done is good enough. Remove distributor cap and the rotor will be pointing at the No.1 wire terminal location.
Any time the distributor is removed from the engine it should be reinstalled so the position of the No.1 cylinder is in the same place, but some mechanics just drop the distributor in the hole and figure out which terminal is No.1 later.
While the distributor cap is off, crank engine a bit to see which way the rotor turns. This will show which direction the rest of the wires go so they fire cylinder 1,2,4,3.
