this guy? number 17?
i do have my fan control set up to power up to half speed ish, when the AC is on, not counting the aux fan i just re added. but i like that other switch idea.... could have saved me some fab time.. LOL. i should be headed to gregs and marks tomorrow, so i can rummage around 928intl and see what i can find.

Jake--
Get the connector too.
And run the fans on high when the AC is on especially with R134a conversions. You may want to shop around for a combo pressure switch with a lower overpressure cutoff setting too. More than 350 psig gets to be too much in a hurry.

from what i can tell the R12 nipples on the dryer pipe/tree are 7/16-20..... does anyone know what the thread on the pressure switch is... i think its m10x1.0

I think that the best system is:
- Add a good relay to operate the compressor clutch, triggered by the original black wire;
- Add a second relay, triggered by the first one, to operate the fan or fans on high.
This can extend the life of the under-sized relay in the HVAC head unit, and gives better AC performance and longer system life by adding condenser cooling.

the cool thing is i have manual HVAC i my car, so it has a nice big relay on the CE panel. but not a bad idea on the fan.
right now I'm searching for a trinary switch with a fitting that will work on the Drier pipe/stock fittings.
