Flex fan harness includes also:
4 – Butt connectors
Heat shrink
Tools needed:
17mm wrench
¼ nut driver
10mm wrench
10mm socket/ratchet
Pliers
Pic or thin screwdriver
Wire cutters
Flex fan harness requires also:
Butt connector crimper

1. Using a 17mm wrench remove the nut from the red battery junction box located on the driver’s side engine. (fig1)
2. Locate the ring terminals that fit the junction box. These wires will be the two red and one white wires. In order to close the red box, you may have to notch out the bottom of it using wire cutters or a hand held razor/box cutter. Secure the 17mm nut onto the stud and close the lid.(fig2)
3. Located just to the left are the two 10mm bolts that hold the junction box to the alternator bracket. Remove one of the 10mm bolts and locate the ¼ ring terminals on the harness. Ground the wires using the 10mm bolt.
4. Located between the junction box and ground mounting point is a group of wires covered by loom. Open up the loom and locate the solid green wire. Using pliers, crimp the provided red tap to the green wire. Locate the green wire on the harness and attach it to the red tap. (fig3)
5. Remove the black cover from the PCM. This is done by pulling outward on the cover and clearing the two plastic tabs. Using a 10mm socket remove the blue PCM connector. This is the connector closest to the engine. Remove the grey retaining cover from the topside of the blue PCM connector. Turn the connector over and using a thin pick or screwdriver, press on the white retaining tabs on each side of the blue-clear cover and remove it. Lubricate the blue PCM wire on the harness. Simply push it through pin 42 until it secures itself. Reinstall the blue-clear cover and grey retaining cover on the PCM connector. Reinstall the PCM connector.
6. Locate the LS1 fan connectors on the harness and install them. Be sure to secure the wires with tie straps.
7. Using the supplied screws, attach the relay connectors to the upper left corner of the PCM cover. Be sure to clear the PCM when installing the screws.(fig4)
Flex-Fan or Universal Fans:
The harness will have four power wires coming from the relays. They are grouped in a wire loom and are attached to your existing fan motor wires using the supplied butt connectors and heat shrink. Be sure to cut the heat shrink to the appropriate size and install it over the wire before crimping the butt connector.
