After some more reading I've discovered that there is an adapter harness that appears to bridge between the 96-99 climate control unit and the factory 95 harness. Looks like you have the 96-99 unit. The 95 units sold today are just a 96-99 unit with the harness attached. Yours doesn't appear to have the harness. Trying to locate the harness without the unit is difficult. I don't believe they sell just the harness any longer. You may be able to find a used one. Looks like the options are 1. Find a used harness. 2. Buy the "95" unit which is actually the 96-99 unit with the harness attached. Link below. Notice the harness attched in the pics. https://www.1aauto.com/1995-heater-and-a-c-control/i/achci00003?f=1023428&y=1995&utm_campaign=gb_csv_br&utm_content=HCI&gclid=Cj0KCQjwrJ7nBRD5ARIsAATMxssnXFBFeJHxqzlUZ_p9cCN-klFyQEkKwcTUTWLBJq1UvD8d3ssR4swaApqcEALw_wcB

I'm also looking for a new climate control unit for a 95 k1500. I don't need rear defrost. I'm having trouble confirming which part number I need. ACDelco 15-72548 This part number above keeps coming up when I Google it. Seems to be a difference of opinion on whether or not it fits 95. LMC has 89-94 and 96-99 available. Does your new unit have a rear defrost button?
