Where can you find a wiring diagram for the spark plugs on a Chevy Caprice Classic?

Answer 1

Your question is not very clear. I am guessing that you want to know how to route the plug wires between the spark plugs and the distributor cap. On GM V engines, the even numbered spark plugs are on the left side on a rear wheel drive engine or along the front of a front wheel drive engine with number one plug being the one at the front of the engine. On the distributor cap, if the distributor shaft and timing chain have been properly installed, the number one plug wire would be attached to the connector closest to the carberator or throttle body. The firing order on GM V8 engines is 1-8-4-3-6-5-7-2
