However, the spark plug wire order on the distributor cap may not directly correspond to that firing order. The physical placement of the wires on the distributor cap depends on the distributor's rotation. You must use a diagram from your vehicle's repair manual or a reliable online resource specific to your 1987 Caprice 305 to determine the correct wire placement on your distributor cap. A diagram will show the number of each spark plug terminal and where it connects to the distributor cap terminal.
Do not rely on a generalized firing order to connect the wires. Incorrectly wiring the spark plugs can damage your engine. Use a diagram to be certain!
