1993 Buick Roadmaster Sedan Keyless Entry Module Receiver Location

Hello, I am trying to figure out the location of the factory keyless entry module receiver, but cannot find it anywhere. Does anyone have any ideas on here? Thanks.

Try looking inside the trunk on the left side. It should be behind the insulation.

The connector for reprogramming a transmitter is located there...

...but the actual receiver is attached to the rear package shelf.
