Having both sets of terminals on one side would be unusual and wouldn't represent a standard distributor cap design for that engine. Trying to wire it according to such a diagram would almost certainly result in misfiring or non-operation.
What to do:
1. Verify the Diagram: Double-check the source of your wiring diagram. Make absolutely sure it's specifically for a 1996 Ford Ranger with the 2.3L engine. A wrong year, model, or engine will give you incorrect information. Look for a reputable source like a Ford factory service manual or a trusted online automotive repair resource.
2. Inspect the Distributor Cap: Physically examine your distributor cap. The terminal arrangement should be clearly visible. It should have terminals distributed around the cap, not clustered together on one side.
3. Find a Correct Diagram: Locate a correct wiring diagram for your specific vehicle and engine. Online resources like Haynes or Chilton manuals often have wiring diagrams, but make sure it matches your exact year, make, model, and engine. A Ford factory service manual is the most accurate source.
4. Professional Help: If you're unsure about any aspect of the wiring, it's best to seek professional help from a qualified mechanic. Improper wiring can damage your engine's computer or other components.
In short, trust your eyes and a verified source. A diagram showing both distributor blocks on one side is almost certainly wrong for your vehicle.
