Xc air con heater box upgrade ?

Recommended Posts

Hi all. I just bought a heater box with interfered ac and noticed a few vacuum operated levers. Has any body done this swap and knows if I have to get different switches or if I can fit the wire operated levers to the new box. I know I will have to relocate holes on fire wall and drill one extra mount but not sure how much more is involved.

Yeah sorry, must of had one too many when I wrote that.

It is going into a xc falcon 500. With had under dash a/c fitted but under dash unit was missing when I bought the car.

The guy I got the integrated a/c heater box from said it was from a xc but didn’t specify variant, it has may 77 stamp on it.

I’m not to worried about the electrical side more more if I need to get vacuum switches for the dash and if the ducting is different

I finally found some pictures on the internet that weren’t blocked by photo bucket, I worked out I will also need different ducting and dash control panel.
