FIRING ORDERS NOTE: To avoid confusion, tag and remove the spark plug wires
one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it
could have been removed previously and rewired. The resultant wiring would hold
the correct firing order, but could change the relative placement of the plug
towers in relation to the engine. For this reason it is imperative that you
label all wires before disconnecting any of them. Also, before removal, compare
the current wiring with the accompanying illustrations. If the current wiring
does not match, make notes in your book to reflect how your engine is wired.
