77xcfalcon 177 Posted October 29, 2017 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. Share this post Link to post Share on other sites
bear351c 10,270 Posted October 30, 2017 Just to be clear, what model/year heater box is it, and which car is it going into.? Share this post Link to post Share on other sites
77xcfalcon 177 Posted October 30, 2017 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 differentSent from my iPad using Tapatalk Share this post Link to post Share on other sites

77xcfalcon 177 Posted October 31, 2017 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.Sent from my iPad using Tapatalk Share this post Link to post Share on other sites
