95 PA to 93 Lesabre climate control swap

[murkadelic]

I have a 93 Lesabre Limited with Dual Zone climate controls (CJ2) [Climate control head C1]
The heater core leaked into my HVAC programmer and fried it so I started hunting around but they're almost impossible to find. I was unable to find any programmers with the same model number as my original one (16182834)
The local junkyard had quite a few buicks but none to match so I ended up getting a climate control unit (C2) and the hvac programmer (16207743) from a 95 Park Avenue Limited without Dual Zone climate controls (C68) [Climate control head C2]
Problem is, the pin locations are incorrect between year models for the programmer and the connector is a completely different style connector for the control unit.
My main question is - is this even possible of a swap before I start removing my factory wires or pins?
And if so, what is the workaround for the lack of OBD II?
From what I can see on my diagrams and what I counted in the vehicle, I'm missing 7 wires for the HVAC programmer and 1 for the control unit.
I do not care about the Dual Zone working. Just want to be able to control it from the main control head. Don't care about the passenger panel or even if its wired in or not.
I attached all of my diagrams and connector views for any reference.
Any help would be greatly appreciated, I'm really trying to get this heat working again.

I don't need a new control unit. I need either an OE programmer (model 16182834) or to be able to wire up a later year model.
Please don't spam me with parts from random places. Only place I'm able to find the programmers are on ebay and they're expensive as f$%k. I got both of these working parts for 40 bucks. Just need help with the wiring

I would say you should NOT try mixing CJ2 to C68
CJ2 to CJ2 sure
C68 to C68 sure.

1993 cj2

you are wasting your time looking for a match part number. They changed the part a lot and that doesnt mean they are incompatible
heres 2 numbers. your 93 have either of those ?

Yes, mine is the 007. Should I be looking at serial numbers instead of model numbers? Maybe that would broaden my findings.

Thank you so much. I guess looking for a "programmer" instead of "temp control module" was hurting it. I've scoured ebay and never seen those lol.
