S13 ac question

[S13alldayyo]

So simple question. What wire connects to the ac compressor? Does it come off the fuse box under the intake on the drivers side? I have a blue wire and 2 other wires that I didn't see the colors.

This should be posted on the small question thread but ill answer your question. It comes off the driver side behind the headlight it has two wires, really small plug.

[S13alldayyo]

Okay so it's the other two wires I splice them together with the compressor plug? What is the blue plug for then?

What you can do is turn the a/c button on and off in the cabin with the key on engine off, see if you get a 12v signal to any of those three wires.. Thats the one at the powers the compressor. only one wire connects

[S13alldayyo]

That only works if everything in the system is running good, then it sends the 12v to the compressor (everything has to be running good and freon in the system as we'll) then it sends the signal :(

no. 12v is power, so as the "key on engine off" you should get power(12v) to one of the wires when pressing the a/c button on and off regardless if you have a compressor, freon or your shoes on.

[ultimateirving]

no. 12v is power, so as you turn the switch you should get power(12v) to one of the wires.

He is right though, the 12v wont send power if the pressure switches dont see pressure in the lines.



Why are you trying to hook it up in this order?
if the vehicle doesnt even have refrigerant in the system what is your concern?

[S13alldayyo]

I'm putting ac in my sr I need to fab up one line and get freon installed, I want everything good to go so they can do the line and freon all in one go

i see. disregard my statement then.

[S13alldayyo]

There is basically 2 different sets of wires that come out the drivers side engine bay fuse box, one has a blue wire to a plug, and the other one has 2 wires (unsure of what colors) just need to know Wich one to crimp up to the compressor

Power wise, it comes out of the main harness in a single wire plug with a little connector on it.

If you want to avoid getting custom lines made, you can always get one of my adapter brackets that retains all of the KA compressor and lines. Much cheaper/easier than custom lines.

I have your adapter bracket and a custom line is still needed, also I have a wiring specialties pro harness I contacted them and they told me everything is ready and the plug for the ac compressor is in your chassis (fuse box) these are the plugs that are coming out my box not sure Wich one it is 62022

its the Blue wire, you can confirm by doing the Key on Engine off, A/C switch on, then disconnect the pressure switch, and jump it with a paper clip.

[S13alldayyo]

Thank you bro I'm just going to crimp it up and as to the fan for the condenser do I just run a wire from the blue one to the fan so they turn on at the same time?

No, the fan that is on the DOHC or SOHC i dont recall if its both of just one uses a temp sensor located in the lower radiator hose for the A/C fan

[S13alldayyo]

I don't have that for sure

down load an FSM for you chassis and check, now if you want to use the compressor wire to turn on a fan you can, however i strongly suggest that you use that wire as a "trigger" for a dedicated relay for the fan.

[S13alldayyo]

Got it!
