Mark,
I believe that the #1 position on the distributor is in the northeast
postition (about 2 o'clock), the #1 cylinder is the one on the front of your
engine. I wasn't sure about the information Bert sent you so I went out to
the garage and checked this (on my car). I think this is standard operating
procedure for most cars, the #1 position on the distributor is closest to the
#1 cylinder.
So just plug in the rest of the wires and starting in an anti-clockwise
direction, take the next wire an attach it to the # 3 spark plug, next one to
# 4, next one to # 2.
You have the right firing order all (?) 4 cylinder engines fire in this order
1 - 3 - 4 - 2.
