I bought an aftermarket keyless entry system that puts out a grounding pulse for lock and unlock. I have a 1998 GMC Sierra which I believe has a 5 wire reverse polarity doorlock wiring. I've been told I need two relays for this to work. Could someone tell me what relays to buy and how to hook it up? Any help would be apprieciated.

You need two Bosch type relays.

You can get them at any radio shack, or auto parts store. You can also get them here for a good price.
