I have a 1993 Cadillac Fleetwood with a 5.7 liter V8 engine. I'm trying to check the ignition timing but I can't figure out how to put the ignition system in bypass mode. It doesen't have a timing connector to disconnect like earlier chevy TBI engines. The underhood decal says to "ground the ignition bypass circuit" but it doesen't tell where the bypass circuit is. Where is the bypass circuit?
