Wait a minute. NO. The number one wire can be placed anywhere you want to place it. What determines where you need to install the wire on the cap is directly related or where the rotor is pointing when the #1 piston is at tdc on compression stroke.

So, with the air blowing out of the #1 spark plug hole, and the mark on the balancer poiniting at the zero mark on the timing mark on the timng chain cover, you take note of where the rotor is pointing and you have to have the distributor cap off for this, then place the cap on and place the number one wire to the spot that the rotor was pointing, then advance it 1/4-1/2 inch ccounter clockwise.

If you do not like to where the rotor is pointing, you need to remove the distributor and stick a long screw driver into the distributor hole and turn the oil pump drive shaft to such a position where you are happy. For instance, the vacuum advance pod may interfere with the fire wall, the intake, or a bracket. Likewise, the plug wires are usually cut at a length where the number one wire needs to be aiming towards the front left hand headlight. So, with the #1 piston at TDC, I would try and have the rotor pointing in that direction.
