aux cooling fan ac pressure switch

[conekiller01]

I don't consider myself much of an expert so don't take my advice too serious lol i would definetly try option C if possible and I would see how that switch works on the condenser by using a voltmeter and seeing if that switch makes continuity to ground when pressure is detected in the condenser? Also at what psi does that switch close? Is it more than what static pressure might be on a hot day? Idk it does seem like the easiest route but only If that switch works the way you want it too

thanks for the reply. i spent hours on it yesterday trying to figure out what i was going to do. i did like you thought and ran the pump while checking the switch to see if it made contact before and after. i couldnt see a difference.... so i gave up on it and bought a relay. i wired it all up and it still didnt work... but i checked a few things and saw that i didnt wire it correctly. but i know what i did wrong. ill have to end up changing a few wires but i think i can make it work.

i still dont know what exactly the switch does on the condenser... but theoretically as long as i straighten the wiring up, it should do what i want it to do... once i get it working, ill post a modified diagram with the relay in the circuit in case anyone else wants to run a setup like this. ill be out of town until tuesday... so hopefully wed i can get back on it. this is really bugging me since im so close to having ac for the first time in 5 years... lol

'Jay, check out this from Brendan at LT1 swap. Shows what you may need. You may have to change a few wires around. Seems easy enough.

Scroll down to about 3/4 of the page. Hope this helps.

thats exactly what i was talking about and how i intended to hook it up. but i miswired a few things which i know what i did. i just havnt had a chance to fix it yet with work and all. hopefully mid week ill be able to get back on it. like i said ill post up the results. thanks
