To find the correct terminal:
1. Locate the distributor cap: It's the top part of the distributor.
2. Identify the rotor: The rotor is the spinning part inside the distributor cap.
3. Find the #1 position: The #1 spark plug wire will be connected to the terminal the rotor points to when the engine is at its #1 cylinder's top dead center (TDC) firing position. This position varies depending on the engine's firing order (typically 1-3-5-7, 2-4-6-8 or a variation thereof for a V6 or V8 respectively). You will need to consult your vehicle's repair manual to find the correct firing order for your specific engine.
4. Connect the wire: The wire coming from the coil (often the thickest one) connects to the terminal in the distributor cap at the #1 position you identified.
Important Note: It's crucial to refer to a repair manual specific to your 1993 Chevy S-10's engine (the 4.3L V6 or the 2.8L V6 were common). This manual will show you the exact firing order and the proper placement of the wires on the distributor cap. Incorrect placement can cause misfires or engine damage.
