914World.com _ 914World Garage _ 914 AC wiring diagram?

Posted by: GeorgeRud May 29 2015, 09:40 PM

Does anyone have a wiring diagram for the 914 dealer installed AC system? I'm finally getting around to installing AC on my 914-6 conversion, and hope that someone can save me time by not having to decider the wiring that I have for the evaporator/blower assembly as well as the front condenser blower circuit.

Jeff's site seems to not be responding right now, but the Wayback Machine has a copy:

About 1/4 of the way down you'll find links to the installation manuals for both the VPC and DPD setups.

Thanks Dave, I knew it was out there somewhere, but also could not access Jeff's site. I'm also investigating the available electric compressor as an alternative to the engine driven one that's difficult to fit in a -6 without hacking up the firewall.

If u come up with electrical compressor let us know. The only ones I could find pulled waaaaay too much power for a 914. Happy hunting and pictures of the install.

Supposedly Retroaire is working on one. It really would be great if the compressor, condenser, receiver/dryer, and evaporator could all be up front to cut down on the length of the hoses.

Luckily, I was able to test my evaporator/blower under dash unit on my workbench with the wiring explained and it blows perfectly on all speeds! The front condenser fan also works, but I want to design ducting that would include both my front oil cooler and an AC condenser in one unit as I already have the front GT opening in the bumper.
