**S14 w/Redtop SR20 and AC Problem!!!**

[midnight_rex]

So i finally decided to hook up all my AC stuff i had just sitting in my patio (which was covered up) in my s14 with a redtop SR20. Im having a problem with the AC clutch to engage when i press the AC button inside the car. so here goes the story...

***im using ALL S14 AC LINES. NO CUSTOM LINES. im also using the S14 KA compressor***

I have everything hooked up and prefectly aligned. the only way that i get the AC clutch to engage is to jump 2 wires from the triple pressure switch on the drier. the clutch would not engage by just pressing the AC button inside the car. Today me a friend of mine jump the 2 wires and hook up a can of freon while the clutch is engaged. freon goes in fine and the air blowing inside the car is cold!!! I figured if i got some sort of pressure in the lines that the AC clutch would finally engage from the signal that the triple pressure switch gives out. I plugged the triple pressure switch back up and still the clutch will not engage. its like the triple pressure switch is keeping the curcuit open and not letting any voltage to the AC clutch.

i even went off a source from Freshalloy's forum which says in quote

This was the simplest part , on the s14 the plug for the compressor is not on the engine harness as for the SR, the s14 has the plug on the driverside fender well , this comes from the main harness that goes by the driverside fender. Well since your using your original compressor you will find that it plugs right in just as it did before. However when you push the a/c button on the dashboard nothing happens. you will notice that all of the other controls work except for the a/c button. you might also notcie if you jump the relay in the fuse box that the clutch will engage and compressor will turno on, but we want it to work like stock with the button on the dasboard. So here is what you do

***** this is the big secret that the wiring people wont tell you ****

on the f3 conector (big white plug under dashboard near passenger foot well , you know the one you have to splice into to make your engine swap work) you need to splice together the following cables pin 16 yellow/ black to pin 43 or 46 (cant remeber now im at work) black/pink. and what do you know voila it works, push the a/c button a/c turns on, pust it again it turns off. 2 friggin wires, it was staring me in the face for like a week before i tried it , it seemed to easy, thats it just sauder those two wires togerther and ti will work like stock.

the only issure is wiring it into the idle air control valve so the rpms wont drop as much but i dont really think that is an issure as i have not had any problems with it yet its not to bad but i already pretty much got that figured out and iwill be doing it at some point later this week i will post it then. hope this helps some of you people sweating in your car, cuz ill tell you here in miami i is hot as biatch"

i did this and it didnt work. i figured that those wires come from the interior wiring to the white plug which goes back to the engine. my wiring was done by 786 motoring here in houston, tx and i found that the yellow/black and black/pink wires were cut intirely from the white plug going back to the engine. i dont see why the AC switch wire and the triple pressure switch signal wire needs to be looped together??? could this be a bypass?? and why do these wires go back to the engine harness?

also could it be a possibility that my pressure switch is no good? how can i check to see if the pressure switch is any good? i just wanna get the AC compressor to operate when i press the AC button inside the car and also operate off the pressure switch.

does anyone here on this forum have a s14 with a redtop sr20 running AC or have the same setup as me??????? i really wanna get this working since i busted my butt getting all the lines in. any info would be appreciated. thanks.
