an on/off was chosen as I cannot use the fan control module nor the fan motor switch to tap the connections. I used the cigarette lighter (+) wire which is ON when the key is in ACC and tapped the wire going to the switch and from the switch to the 85 end of the relay switch(engine compartment) the 86 end of the relay is connected to ground. the (+) battery power source connects to the 30 end of the relay switch and the 87 connects to the (+) red wire of the fan motor. the black wire of the fan motor connects to ground located near/above the fan.

Bringing back an old thread.. just finished this mod last night. :-) Thanks to the OP for the great write up. The fan now comes with a different harness side connector, so I needed a different connector to replace it to fit the HP7310 connector that was suggested. I had to buy this, HP7320 connector which will then connect to the HP7310. I couldn't find the part # for the connector that comes on the fan. :-)

I didn't use a relay, I just hooked the fan negative wire to a switch inside the cabin, and from the switch to the positive terminal of the battery with an inline fuse. The fan can be turned on anytime though, so just make sure you turn it off when you turn off the car. It's hard not to since the fan is pretty loud when the car is off.

FWIW, here's another install with more wiring description and an alternate 6.5" fan.

Looking at it more, this smaller fan looks like it flows more air for similar power. I'm gonna try it too. I'd love to figure out a good auto temp switch for it. Open to suggestions...
