Do I have keyless? I have looked.

@Caman96 This is a piggy back question, have you personally considered adding a theft deterrent kill switch? I'm not that mechanically inclined to understand whether or not, having a kill switch would prevent the remote start to work. I'm almost certain "wiring it the right way" is an acceptable answer, just haven't seen anything about it combined.

Look through these and see if one applies to a remote start or not. Or maybe someone else can jump in.

Just to clarify, don't let terminology trip you up - you have manual A/C. What they mean is that it doesn't have an automatic setting where it determines temperature and fan speed for you - instead, you set it, i.e. manual. All the 88-94 factory A/C GMT400's have the digital controls.

I have AU3. I have read online that some 1993 models had it and tahoes and trailblazers. I read in some forums on here about AU0. I would like to retrofit it I don’t have it.

I thought you were looking to add keyless entry.
