On a 1975 Dodge 440, the number 1 spark plug wire typically connects to the distributor cap terminal that is aligned with the number 1 cylinder, which is located at the front of the engine on the driver's side. The firing order for this engine is 1-8-4-3-6-5-7-2, so after placing the number 1 wire, you would follow the firing order counterclockwise around the distributor cap. Always double-check the specific configuration for your engine, as variations may exist.
