This is a link with a diagram on how Ford counts cylinders and how to identify cylinder number one. All Ford engines, whether mounted horizontally or longitudally, are counted the same. The front of the engine is always coming off the crank/balancer.

Once you know how to count cylinders, match the coil pack wireds to the cylinder following the firing order I posted above.
