[DeTomaso] 3 connector v 2 connector AC De-Icer Switch

[Julian Kift]

On the electrical diagrams I don't see the de-icer switch as anything other than a simple 2 terminal on / off thermostatic switch, to stop the system from freezing when it reaches the desired set point. On early cars AC is wired so that the condenser fan only comes on with the compressor and later cars the condenser fan runs whenever the AC system is switched on.

Look at SoBill's A/C electrical diagrams on Mike Dailey's Panteraplace, there's a modification to add a Bueler 508TD time delay relay so the condenser fan will run on a fixed period on early cars.

Working to source the parts for my AC and have realized that my AC switch,
referred to on Wilkinson's and Stock's sites at the AC de-icer switch, is a
two-connector version that does not provide proper control of the condenser
fan.  The stock switch has three connectors which provide for independent
control of the condenser fan, allowing it to keep running after the pump
de-clutches.



Wilkinson's site listed the original 3-pin switch as 'no longer available',
and Larry Stock told me that the last three times he's ordered the switch,
they send the wrong one (2-pin) and he'd had to send them back.



Does anyone have an original 3-pin switch with the copper tube and copper
sheath?  Or, if you've had to install a 2-pin switch, what have you done to
allow the condenser fan to keep running after the pump disengages.



Thanks
