Was just thinking... If I got another controller could I maybe fix it to the condenser or one of the AC lines and set it to come on based on their respective temps?
I thought about it and how you could best make it work. I don't see why you couldn't run the probe to the condenser. With the wide range of temp adjustment, it should work fine. Or just trigger the ac fan relay from the ac fuse? Use a fuse tap and when that fuse circuit sees voltage it will trigger a relay run to your fan choice?
So i'm sure this forum is kind of dead by now, but i was just wondering if anyone had the link to where i could get the wiring kit from?? None of my local parts stores even know what im talking about.. But I pulled some old E fans from the attic in the shop i work at, and I've really been wanting to throw them on. Any help at all would be nice, thanks!
You need:
2- 30/40 amp relays (1 for low speed and the other for high speed)
2- inline fuses w/30 or 40 amp fuses
some 14awg wire.
this temp controller from AZ: http://www.autozone.com/autozone/par...=267187_9581_0
Use any Red/lt green for the on signal, I used the one at ICM.
Relay one:
87>High Speed
30>Battery
85>Controller (temp sensor)/if you have ac you can also connect another lead to it's power wire
86>Ground
Relay Two:
87>Low Speed
30>Battery
85>Remote switch in cab
86>Ground
Temp Sensor/Controller:
2>Red/Lt Green wire (any wire that's Red/Lt Green works) @ ICM
C>Terminal 85 Relay #1
To house everything (relays) you can pull any double relay box at a JY, F150 with tow packages have a double relay housing or just check until you find one, I found this for mine:
Ummmm NOPE! 14g is way too light of gauge wire. 14g wire max is 20a. 8g is easy and cheap and handles about 45a.
Advanced Auto parts sells the fan controller that is adjustable for $18. Also, are you running air conditioning? If not, only one relay is absolutely needed. I run one per fan for redundancy. One fan fails, the other will keep the truck running cool. Regardless of the type of fans that you have, you have to make sure that you have ample amperage to run them. I suggest the 3g 130a. If your running a factory type twin fan from a sedan, you will probably have two speed fans. You can run low speed on both, suggested for the ac fan, and be perfectly fine. If you run high speed on the ac fan continuously, you risk a dead battery in short order at idle. Low speed will cool the ac condenser just fine. Low speed thermostat controlled radiator will also cool just fine. Runs for a few more seconds over the high speed fan setting, but at just over half the amperage.
I was referring to the signal wires, which carries min. amperage. For the relay>fan I just used the wire on the harness/socket and the original fan wire. The inline fuse was 10awg with a 30 amp fuse. I figured most people would reuse the original wiring that is on the fan and the relay socket so I didn't think to specify, sorry for any confusion. I used this type of inline fuse:
I used 14 and 16 ga wires on mine and have had 0 problems, the draw is not that high, I think I'm only running a 15 amp fuse for the whole thing ( but then again I'm only running one fan)!
I do have air conditioning yes, I just really have no idea what I'm doing when it comes to swapping my fans, I've done every other mod on my truck but for some reason this one seems more intimidating. I just need a basic list of materials, where to get them, and the forum starter posted good enough instructions I think I should be good off of those, but anything would really help. Thanks! And in case I didn't mention earlier, these are chrysler fans as well, duals. Probably came off a van or sedan..
You have several options with the Chrysler fans. If the wires are black, green, yellow, then you have two speed fans. They can be wired in any combination you want. The black is ground of course. Ground the black wire and connect the wires to your battery to explore the combinations. I would wire one fan to the ac switch on low speed. Wire the other to an advanced auto parts controller on high speed. With the cfm of the Chrysler fans, there is no need for high speed dual fans on the ac condenser. A single low speed fan is more than adequate if your cooling system is working correctly. I'm working until Friday night and fighting my cell phone keyboard, so please excuse any spelling. You'll need a fan clutch removal tool for a part store. Most rent them for free. Run that single low speed to keep the ac cold. Got to run, 911 call.
