The red wire with white tracer seems to supply +12 volts to the fuse box.

Also add....check out the red tek thread. Terry K has been so helpfull, all the info there would apply here. Clean the lines with air brake antifreeze.

This makes the most sense from the length of the hoses that I pulled from the other van. Is there a reason why I shouldn't route it as instructed?
"Cut an opening in the floor grommet in the tunnel located under the heater box and insert the condensation drain tube. Route the tube behind the R.H. heater outlet and connect to the evaporator drain".

I am wondering why you would route the drain line over the radiator and fan? Thanks for all the responses.

I recall a "T" and an "L" fitting that connected the two and then drained out the cabin through a hose through the body.


I think that the instructions mean you connect a 90 degree fitting on the right side drain, a "T" fitting at the left side drain, and pass the drain hose through the same grommet that sorrounds the heater hose that goes through the firewall. From you pic, it looks like there would then be enough slope to drain the evaporator by gravity.

I did not see in your thread whether you are going to run R134A or Red Tek. I strongly suggest Red Tek to keep head pressures low and cooling performance up.

The yellow lines in the pic below show what I think the instructions are trying to tell you:

I've got the same setup in my 84 Westy. Worked until last summer on R12. Time to fix it this year....

Thanks for all the help and comments. I have the drain line installed now as well as all the wiring, evaporator, and condensor. I still need to install the compressor and run the hoses (and 1 wire) up from the engine to the front of the van. I am starting to think more seriously on how to route the A/C vent louvers. I am looking at 3 options and would appreciate any input on why to go with one over the other.

Option 1, mount the behr a/c vent to the right of the stereo;

Option 2, mount round vents to both sides of the ashtray;

Option 3, mount the behr a/c vent in the stock stereo location and install a double din stereo / gps in the stock ashtray location. I have one of these in hand and it is the same width as a stereo receiver. I would need to cut out the bottom of it as well as the dash pad below it. I am just concerned that the double din would stick too far down and hit the heater box. If it didn't, this would be a great upgrade. Imagine it without the vent in the photo.

Any input on why one of these options might not work would be appreciated. I am leaning toward option 1 at the moment as it looks the most stock.

From experience, on a hot sunny day, you will need as much AC blowing directly on you as possible. We are using the factory side dash vents. You get decent air flow out the side vents, but not enough to cool the front area. It is the center vents that really do the cooling work. I don't have a behr unit, but opted to put two center vents in my radio slot. One for each passenger. The combination of the side and center vents makes it comfortable, but by no means an icebox. I am using a clarion radio with a remote head mounted to my headliner.

Just curious how the stereo is anchored. I just have mental images of audio equipment missiles in the air in the event of a collision. Overhead installations brings them closer to where it might just hurt. Wink

BenT, In an acccident, my wife, the dog and I will be burried by all our stuff. The hope is to not have an accident. The clarion stereo is from the Marine application. The peice in the picture is really just a display/controller. Less mass than a GPS. The actual unit with all the working parts is secured to the tunnel behind the center panel. The display is attached to the 30 year old wood headliner with two 5mm bolts and nuts. I think the mirror in front of it is more solidly mounted, but thank you for your concerns.

I could have mounted the display anywhere, but wanted it where I could see it while looking out the windshield but out of plain view. The stereo was an after thought. The factory stereo was removed during the AC install. I was actually looking at a SecretAudio Stereo, but it had mixed reviews. Clarion has been in the business for a long time and to hold up to a marine application made good sense for our vanagon. I was limited by the display cable length where I could mount the chassis and the head. I ran the cable up the p/s A-pillar along with new new speaker cable. Pretty tight fit.

I agree with this assessment. My dealer installed Behr pumps a lot of air out of the centre vents directly onto the front seat passengers. For me, mounting the stereo on top of the dash was a small price to pay to have effective AC.

It turns out that having the radio higher up makes it easier to see and operate, too. Wink

rsxr- Is your stereo the Clarion CMS1? Does it have a CD player?
Jake - Do you have any photos of your dash with the stereo installed on top?

Thanks for the input.

I too would love to see pictures of creative ways to mount a stereo. My behr ac is also installed with the two center vents dedicated to ac. my van dosen't have a stereo, and we are trying to think of placed to mount one.

Yes I believe it is the CMS1. Unfortunately for my wife, no CD player provision. She likes books on CD. I have to rip a audio book to a thumbdrive before we head out. The unit reads thumbdrives well. A little difficult to navigate subfolders though. Probably me.

It does have a dedicated iphone input as well as a dedicated Sirius/XM input. I have not used the iphone input, but did purchase the cable. I am using the Sirius input. It works well, the Sirius dock is mounted in the glovebox and you control it all through the Clarion head. I assume the same would be true for the iphone.

Another cool feature is it has built in weather band. When in range you can get up to date NOAA weather broadcasts. mark

I have pix of the JVC up top somewhere - I'll put one online when I get a chance.

The JVC CD Receiver that I have is a terrific unit and will play almost anything you throw at it with its disc reader, stereo mini plug input and two USB ports...

Here's a pic of my previous Eclipse CD Receiver mounted on the dash via the dealer installed radio/cassette holder and some homemade brackets. I originally moved it up there because the CD player wouldn't work at the extreme almost vertical angle that the cassette player was mounted at. The CD player's been up top for 6 or 7 years now with no apparent ill effects.

I have completed my install and have been working out some small kinks. Everything seems in order now. In case others want some additional photos for their own install, I added mine to a Shutterfly website. This was a BIG project that I am happy is now done!
