@davidnunn posted:There wasn’t one from the factory. Pantera’s tended to rupture A/C hoses or blow the ends off hoses, if the car was driven at high speed for a long period with the A/C on. System pressures would go too high without any safety mechanism being in place. A binary switch will disengage the compressor clutch if pressures go too high or too low.
The easiest way to install one is to put it in the drier. Most driers have an unused port that the switch can be installed in. If you’re building a new system, you can also get in-line binary switch ports.
I just redid the whole A/C system and got it charged… here is what I just ordered… I think I can install it without evacuating and recharging…
