How does coil hook up to Cap on 1985 Corvette?

The ignition coil in a 1985 Corvette doesn't directly connect to a capacitor in the way some older ignition systems did. The 1985 Corvette uses an electronic ignition system, and the capacitor's function is integrated into the electronic control module (ECM) or a similar component within the ignition system. There's no separate, externally mounted capacitor you'd wire to the coil.

The coil itself connects to the ignition system in this manner:

* Positive (+) Terminal: This receives the high-voltage pulse from the ignition module (part of the ECM or a separate ignition control unit). This is what fires the coil.

* Negative (-) Terminal: This is connected to the distributor cap via the coil wire. The distributor cap distributes this high voltage to the spark plugs through the rotor.

In short: You don't hook up a separate capacitor to the coil. Any capacitive elements are internally managed within the electronic control system. If you're experiencing ignition problems, the problem likely lies within the ECM, ignition module, coil itself, wiring, distributor cap, rotor, or spark plugs, not a missing external capacitor.
