How to program 94 Cutlass remote key bob

Can anyone tell me how to program a remote key bob for a 94 Cutlass? I bought one off Ebay and need to program it. One post said to dig around for a wire in the trunk by the antenna and ground it but it wasn't specific enough. The local dealer want's $40 for the task. Any help is greatly appreciated. Thanks.

My '95 is a black wire with a white stripe and a black connector. The connector is just hanging loose by the point where the power antenna goes through the fender, behind the trunk trim panel. It comes out of the harness that goes to the rear of the car.

Thanks jmblimo, I found the wire, now just need to figure out how to get both remotes working, when I grounded the connector, the locks cycled and the new remote started working and the old quit. I need to get the old remote to work now. Thanks again.
