92 Silverado Timing

Can anyone tell me on my 92 5.7 Silverado exactly where the wire that is needed to unplug to time my truck is located? Thanks For anyone that can help.

I believe it's in the engine compartment on the firewall. Should be under some black plastic box with a bunch of other wiring.
