INSTALLATION
*Start by disconnecting the Negative wire (-) from the battery.
*Disconnect & remove intake pipe from Intake manifold and air box unless you have AM cold air intake.
*Now with the intake pipe removed, Remove the bolts that secure that Fan Shroud should be two on top and one on the bottom securing it to the radiator.
*Once the Shroud is loose, begin to loosen the nuts holding the Clutch Fan in Place, Once you remove the clutch fan (you may need to adjust your belts being loose do to the removal of the clutch fan).
*Remove the Fan Shroud.
*Now with the Clutch fan and Fan Shroud removed.
*Disconnect radiator hose from radiator and point up so you don’t lose too much coolant move any wires, cables and hoses that may interfere with your install.
*The Stanza fans are very close to size with the OEM S13 radiator but you will need to test fit and trim the plastic around the fans so that it will fit (where the upper radiator hose attaches to the radiator you will need to trim the fan plastic so the hose will not have any problems attaching)
*Once your fans have been trimmed and test fitted you'll want to zip tie the fan to the radiator or radiator bracket so that it doesn’t move while finishing your install.
*Locate the Black & Green wires on the fans you'll be using them for they work for pulling, the other two wires you can cover up with electrical tape or caps.
*The Hayden adjustable Thermostatic temp switch has its own instructions. I mounted this switch in the top in the middle of the E-fan plastic.
*There's a metal probe that’s attached to the switch, with the mounting supplies provided
mount the probe on the radiator under the upper radiator hose for which this is one of the hottest areas (I know that some have even mounted it inside of the URH)
*With two female spade connectors, Run and connect one wire for Dirt (-) and the other will be for Power(+).
*Run the Power (+) wire from the fan to the © on the switch
*Run a wire from the (2) on the switch to the In-line fuse holder & connect to the battery
*Mount the ground wire to a unpainted part or screw on the chassis, I attached mine to the screw on holding the radiator bracket.
*30 amp switch has three prongs Led, Power (+) ,Dirt (-) (I purchased one that had an L.E.D light.
*LED find a wire such as radio with constant power and connect so the light will turn on
*Dirt (-) find a screw and and secure it (I used the screw on the foot rest)
*Power (+) run wire to the relay located in the fuse box in the engine bay.
*note: you dont need to plug in the LED for it to be functional*
*The Relay has four prongs,
*From the relay run a wire for Dirt (-), here where I ran mine.
*Run and connect a wire to the In-line Fuse Holder attach to the positive (+) on the battery.
*Run the power (+) wire from the fan in to the relay,
*Run the power (+) wire from the switch to the relay,(to keep a bit clean run the wire through firewall along the wire loom through the wheel well in to the relay.
As I research the install I took as much information from different forums to get and idea of what I needed to do here's a few of the sites I went to just for further reference:
