on a 06 A1R, where is the 24 v supply that the 2 wire plug goes to? that is the orange and black wires.
I have the evaporator coil from a MRAP which is rated 33,070 BTU, the gen 2 is just a little larger so I would assume at least that rating.
Thanks, Tom

[FONT=&quot] If my memory serves me the two wires in the plug one is 24 volts and the other one is 12 volts . [/FONT]
[FONT=&quot]( not switched power is on all the time ) on the lmtv Gen 2 air conditioner only uses the 24 volt wire . This seems to power the servos that regulates the Heat , air Direction servos, AC compressor clutch and condenser fan motors . The original truck wiring harness provides 12 volts for the evaporator fan and panel lights .[/FONT]
[FONT=&quot] Hope this info helps! [/FONT]

thanks and please change your font to white, black is almost impossible to read.
Sorry that does not help, and that info is not correct anyway. The 2 pin plug is just 24 volt and ground. The 4 pin plug is 12 volt illumination and 24 volt for the blower and 2 ground wires. I need to know where in the PDP the 2 pin, orange and black gets the 24 volt for the compressor and condenser.
I would have almost thought the A1R would already have a connector since it is the only model meant for A/C.
