[DeTomaso] Air Conditioner solenoid on carb

[RKMosier at aol.com]

I never put a solenoid on my Holley 650 carburetor when I installed it for  
the a/c to kick the idle back up when the a/c comes on.  I contacted  Holley 
and they gave me the part numbers to use.  Having never done  this before, is 
there any advice before I go buy the parts?  I was looking  at the wiring 
diagram on the Pantera Place Web site and am not sure which wire  hooks up to the 
solenoid.  I have a 72 Pre L.
 
Thanks in advance for the help,
