Wiring ls1 efans help....
Im having problems wiring the ls1 efans on my truck. I've got everything hooked up and installed except the hot in run wire and the a/c wire. Looking at agreifs site pic #32 http://james.jaguar.net/agreif/fans/fans32-AC1.JPG Is that the green A/C wire I need? Oh, and where did you guys wire the hot in run wire? I was thinking about wiring to the headlights, but I dont know where to find the wire.
BTW, Im using the 3 relay schematic...http://users.adelphia.net/%7Esnakeoi...03%20relay.gif
Thanks. Laters

The green wire in the aforementioned picture is the supply voltage. If you use this wire, it is not compatible with the schematic. If you use this wire the schematic should change to have this wire go to the 86 pins on Relay2 and Relay3. Pins 85 on these two relays will then go to ground.

That is the green a/c wire you will be using. You don't need to tap into an ignition wire. Just have whoever programmed your truck with HPTuners to set at the desired temp you want onn/off from pin #42 on your pcm. You can get the hot wire from your battery or that red+ box close to the alt.

Battery voltage should only be used as power supply for the relays (pins 30). The only reason to use battery voltage for the relay control (pins 86) is if you want to be able to energize the relays when the truck is not running, otherwise a switched supply should be used.

Here is what I've got... I need to wire the "A/C clutch compressor circuit" wire to the B2 (A/C comp supply voltage) in the picture so the efans turn on when I turn on the engine; and the "hot in run and start" wire goes to the C4 (ignition source). Is this correct...Just making sure, I don't want to mess anything up. Thanks

Thanks for the help , but I already wired the fans using this other schematic http://users.adelphia.net/%7Esnakeoi...03%20relay.gif Where or how can I find the (Dk Grn/Wht Ckt 459) wire?

Looking at the picture, that's column 4(from left), row 3(from top) - hence D3, of that connector.
