I have been trying to replace the heater core from my 1993 Pontiac Bonneville SE but I have had no luck. I was wondering if anybody has done this job before and can help me with some instructions or even some pictures to guide me in the right direction. Thank you.

I'm "too lazy" to dig it up, but there are numerous threads on that topic. Just be sure and ground the core after it's installed in the event there is any stray voltage running around in the car. If there is, it will cause the core to fail pre-maturely. - BC

It it's anything like a Ford, you need to tie the new heater core onto a wire and dangle it from the ceiling of your garage. Then you need to assemble the car around it.
