In the days before electronic fuel injection, the Chevrolet 350 was a popular engine choice for many automotive enthusiasts. But deciphering the wiring of this era’s classic models can be a challenge to even the most experienced of mechanics. Today we’re doing a deep dive into the 1985 Chevy 350 distributor wiring diagram – shedding light on the intricacies of this vehicle’s innards.
The 1985 Chevy 350 distributors all had female spade connectors with one or two male spades. This was the standard at the time and all Ford, GM, and Mopar distributors followed this layout. The key is to make sure you pay close attention to the order in which the spark plug wires are connected. They will all have different lengths, so lay them out beforehand based on the diagram that comes with your parts kit.
To start, let’s take a look at the “primer” or power wire that goes from the ignition switch to the distributor. This wire will have a pink trace and will have a 20-amp fuse in the middle. Once the primer wire is connected, it’s time to link up the wires that control the ignition module. These will be color-coded according to the manufacturer, but they should all have one or two female spade connectors.
Now that the module wires are connected, let’s move on to the spark plug wires. This is where the diagram becomes helpful. Lay out the wires according to the labeled diagram and make sure the connections are snug and secure. This will ensure you don’t cause any faulty connections or create an electrical short. Once you’ve connected the spark plug wires, the last step is to connect the negative ground wire to the body of the engine.
Overall, the 1985 Chevy 350 distributor wiring diagram is fairly straightforward, but like all wiring diagrams, it pays to study it carefully before you start tackling the project. With some patience and attention to detail, this classic setup can be wired successfully and is sure to provide reliable performance for years to come.
