Factory alarm and aftermarket HU?

Will the factory alarm still work? Since the settings are typically done through the stereo, is it the alarm itself, or just a setting entry point?

Thanks for any input.

The factory radio on the 4th-gen f-body is just a radio. The alarm settings do not go through the radio.

LOL, my bad then. I have had the car since new in 98 and could have sworn they did. I thought I set something up way back then.

Good to know.

My electrical system is heavily under the knife. A stock PCM running the ABS, HVAC, fans, gages, then the engine is run by Big Stuff 3 and I have the new stereo. I hope it all works.

Probably was pulling the Radio fuse to enter programming mode.

You may have activated TheftLoc which is a security feature built into the factory headunit itself, independent of the factory alarm.
