I cant seem to find any referance to how the plug wires are configured or layed out on the 1987 Grand National, particularly in terms of where they go on the coil pack Help!

Front of car


First plug on driver's side front is 1, first on passenger's side front is 2.

Coil is numbered. If installed properly, it should look this way. Will still work if installed 180 degrees out (even wired 180 degrees wrong) since it is a waste spark system and fires two plugs at a time.
