Where do you find the electronic spark timing bypass on a 1992 Cadillac 5.7?

On a 1992 Cadillac 5.7, the electronic spark timing (EST) bypass connector is typically located near the ignition control module. It is a single wire connector that can be found on the harness leading to the module. To access it, look for a two-wire connector; the bypass is usually the single wire that can be grounded to bypass the EST for diagnostic purposes.
