Anyone familiar with this kit or have someone install the unit and successfully have it running?

My kit is for the 1966 Mustang and after reading the instructions Classic Auto Air provide (not all items & instructions relate to my current kit). Anyway instead of a "sight glass" I have a "pressure switch". On the pressure switch there is 2 prongs for a connection...one goes to the compressor clutch and the other go to the "blue" wire on the "under dash unit (evaporator)" per instruction. The "Red (hot wire)" from the under dash unit connect to the supply side of the heater fuse per the instruction. And last but not least the black is the "ground".

Well, after following the instruction thoroughly, I cannot get the under dash unit to power up, not even the motor spinning. Maybe I'm dumb and should wait to do the power up until I get the system charge? :shrug: Tell me if this is correct so I don't spend the whole day trying to troubleshoot something and drive myself crazy not knowing what it is.

According to Classic Auto Air...the under dash unit have either a "inline fuse" or "circuit breaker". Does anyone know which one it have and where? I looked at mine and cannot find it. Maybe the fuse (if there is one) blown or I need to reset the circuit breaker. :shrug:

Sorry for the long post.
Thanks for the help.

The unit may not power up at all until pressurized. On newer units, the pressure switch only effects the compressor. Yours may effect the entire unit. You can jump that pressure plug to test the system but do not run it to long. System needs oil and to be serviced before running for more than a min or so. The best way is to get it serviced.
 
Streetstang..so your saying that the underdash unit should work prior to charging?

I checked the electrical connections a dozen times and still no just from either under dash unit or the clutch. I can even tell you exactly what color and where to I connect the wires. Did you have a pressure switch too? Was there a black connect with 2 white wires coming from it? I take it that goes over the pressure switch and 1 white wire connect to the red wire from the clutch and the other white wire connect to the blue wire from the under dash unit?
