Very precise a/c problem... help :/

[duty780]

Hey everyone. I have an s13 with a red top sr swap. I am currently using an sr compressor. My a/c works perfectly. The only problem i am coming across is that when i turn on the a/c the idle is supposed to raise. Its not raising which is the reason why it idles at 400-500 rpm when a/c is on. What did i miss when i did my wiring? I apologize if it has been covered previously. I searched and only found bracket problems and this and that. Thanks in advance for your help. Your knowledge is greatly appreciated.

I think there shoud be a PSi switch that commands the ecu to bump up the idle, or a relay thats connected to the switch?? Not really sure, to tell you the truth.

thats what i am thinking too.. but i need to know where it is.... i know the one that turns the compressor on and off.. that one is on the dryer.. i just need to know which is the one for the idle...
