I'm beginning the installation in my 70 non-factory air Dart. I bought the perfect fit with the blue tooth diagnostics. It came with Installation Manual 1967-72 Chrysler "A" Bodies, Document #1-3062 Copyright 2021 ClassicAutoAir / 07.21
The booklet looks to have been designed by somebody in high school. It's not totally awful but it's also not great. One example is an illustration on page 23. It shows the installation of the heater box from the engine bay view. It's showing you to use two supplied bolts to bolt the box to the firewall. The problem is that it looks like you will have to drill two new holes with no instruction on where. After careful examination of the heater box and the firewall, you realize that you are to use two of the existing holes from the old fan motor.

Another lack of explanation is Bench Calibrating the system before installing it in the vehicle. Pages 9-10 are titled "Operation" and show all the positions of the controls and what should be happening with the unit. Then you get to the middle right of page 10 and it reads "Your controls are now fully calibrated to your unit...." Wait, what? We were calibrating? How? And on one of the bags in the box it says you must follow the steps in the BENCH CALIBRATION packet before installation. There is no packet for that. I was poking around their website and under "Support" I found a video on how to bench calibrate. The installation manual looks like it was not written by a technical copy writer and more like something that was deemed to be too long so they edited it down and then never went back to proofread it to see if it made sense.

I also found that my temperature slider only has half the range of travel. I looked at the supplied Temp Control Integrator, which is a sliding potentiometer, and it only has half of its range of travel as well but the opposite direction. If I shorten the wire 3/4" and make a new loop, both the temp control slider and the Integrator will have full travel.

I'd be interested in hearing any other experiences on installation of the newer system. I expect to have to do a few modifications but leaving out important information is not so good. I mean how difficult to print, "IT IS MANDITORY THAT YOU CALIBRATE YOUR SYSTEM BEFORE INSTALLING IT IN YOUR VEHCILE. VISIT THE SUPPORT PAGE ON OUR WEBSITE TO VIEW A SIMPLE HOW-TO VIDEO"
And the bolts through the firewall, it would just take a few dashed lines directing the bolts through the two holes on the drawing to illustrate that. Simple.
