A/C on/off switch Wire?

[azlifer]

Hello Everyone! Go a quick question. Just finished putting a few mods on my 05 H2 and was wondering where this A/c Wire is? I put dual Fan set up on but Parma-cool didn?t get specific on where the a/c on/off switch wire was. Fans come on ok when temp is right but not when a/c is engaged? Any clues? I also put on airrad duct with volant cool air box and Jet MAF. Oh yea and Magnaflow Dual split exhaust!! Sounds sweet but a little close to Air bags on passenger side!!

Any help would be appreciated!

At the compressor

[azlifer]

kind of knew that but was looking for a closer position than running the wires down there. How about the a/c dryer? there is a blue and black wire on it.?? any luck there? wish i had an amp meter o:lame: r light tester. damm i cheap!

[KingVinnie]

always use a meter! light testers are no good and can damage electronics in the newer autos. Dont know about the dryer. I assume your looking for +12v when the AC is on. I've always seen them hook to the compressor wire.

Which wire? the black or the green?
