Default Timing procedure help

The FSM says to look at the engine information label for my 90 L98, no luck it is gone. If you have that information I would appreciate your assistance. The manual says to disconnect the ECM (the four prong connector I think) connection. I do that and the engine won't start. Where am I going wrong. Thanks Jack

you will need to disconnect the est located in main wiring conduit near the brake booster (brown wire), the sticker all states setting base timing @6* in drive.
