https://drive.google.com/file/d/0B3h8j6sXR813blBiY05haDVJcWc/view?usp=sharing I have a 98 EJ22 in my 92 Loyale Wagon. I put in a D/R tranny, gave it a 2-4" lift and just last week put on the stronger springs that JesZek suggested along with all new struts and all new 1/2 shafts. She's running pretty awesome! But first! I need my AC for the upcoming hot summer! I scavenged all the R-12 parts out of a 93 Legacy (compressor, compressor bracket, tensioner pulley, lines, receiver/dryer/pressure switch) and paid Mac's Radiator here in Portland a large chunk of change to mate all the fittings together and integrate it into my Loyale (so it hooks up to the Loyale condenser and evaporator. They also ran through the system, changed out O rings, flushed and pressure tested it. They said it's all clean, flushed, the compressor seems to work fine, the system holds pressure and they also replaced the drier. Unfortunately they wouldn't put R-12 in it until I re-installed the Sub Fan and got it wired correctly. So I've spent the day searching for all the different wiring diagrams for each donor car and locating most of the necessary wires from the EJ ECU. I already have 2 fan relays that I set up. Plus 2 slim fans, pulling from the inside of the radiator. The main fan is switched on with Pin 74, a Red/Blue wire that goes to ground when the engine gets to about 90 degrees C. I was told the sub fan is switched on with Pin 73 after an even higher temp is reached. Pin 73 is a Green/White wire that I tried to use for my 2nd fan. It never seemed to work no matter how hot I got the engine so I ended up wiring a toggle switch next to the steering column for its relay. My understanding now is that it (Pin 73) is grounded when the A/C is turned on. My goal is to get the A/C wired up properly, so that the ECU does what it needs to do: Kick up the IAC for 1/2 a second and then switch on the A/C compressor relay and fire up the Sub Fan simultaneously. I would like to run the compressor trigger line on the A/C relay through the pressure switch on my drier so that it has that as a backup safeguard as well. I will also run the toggle switch to the A/C relay ground so I can keep manual control of the 2nd fan as needed. Here are my questions: Where on my 92 Loyale can I find the wire that is activated when I press "Defrost" or "A/C" on my dash? Is it grounded or hot when I turn on the A/C? If it's hot like I imagine, then I want to run this +12v wire to the hot on my A/C relay, and to the compressor trigger wire via the Pressure switch and A/C relay contact? I am assuming that Pin 31, Blue and Orange will provide the ground to fire the A/C relay and turn on the compressor. I'm also assuming that Pin 60 receives a +12v signal from my A/C "on" hot wire when I hit the A/C buttons and this gives the ECU the heads up that I'm calling for A/C so it can do it's job. Right? So, yeah, my biggest questions are: Where can I find the A/C wire on my Loyale? and is +12v the correct voltage to input into Pin 60 on my ECU when I call for cold air? Hopefully my link above shows the picture I drew of what I intend to do. Can anybody confirm or deny my ideas??
