1994 Mustang GT Remote Keyless Entry Programming?

I have a 94 Mustang GT Convertible Keyless entry remote control question. It has an aftermarket remote FCC ID: BGAPRO2T. I bought an indentical new replacement remote which is an Audiovox I guess. It says Pursuit on the case. Its a 2 button remote.

How do I program the new remote to operate the alarm and doors on the car?

Thanks...Speedster351
