[DeTomaso] Late "L" model (#7102) A/C wiring

My GUESS is the factory ran out of the three terminal controls and  used a 
control from the early cars.
 
My second GUESS is that the external part is a fixed temperature  thermostat 
to control the AC clutch. But, who knows?
 
BUT, the control SHOULD have a power input pin and temperature  controlled 
output pin. I would pull the Blue/Black wire off the control and  connect the 
White/Black wire. This should energize the compressor clutch if  the the AC 
Clutch relay is OK.
 
If your compressor clutch works in the above test, you could wire  the car 
like the early cars by using a splice to connect the Blue/Black and the  
White/Black to the same terminal as Blue/Black is now connected. This will cycle  the 
condenser fan the same as the compressor clutch.
 
Here's how to make a splice:
 

Go to a Radio Shack-HomeDepot-OSH-any hardware store and get  some stranded 
hookup wire ...... 18 Ga will be fine. I always use Yellow for  this sort of 
fix  ..... so it will stand out.  Get some red colored  male and female 0.250 
insulated crimp on lugs. The Blue/Black wire which  goes to your switch and the 
White/Black which goes to the mystery part  have female terminals. Into a 
female terminal, strip and crimp two  pieces of wire each about 4 inches long. On 
the other end of each wire,  strip and crimp on a male terminal. This will now 
be a sort of "V" looking  affair with a female terminal at the base of the 
"V" and two male  terminals at the branches of the "V." Plug the female terminal 
into the male  terminal on the switch and connect one male terminal to the  
Blue/Black wire and the other male terminal to the White/Black wire.  You are 
now wired like an early car.

 
Or you could get a three terminal control from one of the vendors.  The 
aluminum tube terminates in a temperature sensing bulb inside the  evaporator.
