    I assume you have a V8? Here is a diagram of the cylinders.

I changed my spark plug wires and possibly have them connected wrong. Is there a schematic that I might follow in order to ensure they are connected correctly?


FIRING ORDERS NOTE: To avoid confusion, remove and tag 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. Fig. 1: 1988-95 4.3L Engines Firing Order: 1-6-5-4-3-2 Distributor Rotation: Clockwise 91022g01.gif
Fig. 2: 1996-98 4.3L Engines Firing Order: 1-6-5-4-3-2 Distributor Rotation: Clockwise 91022g02.gif
Fig. 3: 1988-95 5.7L and 7.4L Engines Firing Order: 1-8-4-3-6-5-7-2 Distributor Rotation: Clockwise 91022g03.gif
