How to wire your cooling fans on a switch easily
I found a way on 07-08 R1's to wire the cooling fans on a switch so you can turn them on when you want and they will still turn on and off like on thier own like stock.
All you need is:
1. a couple feet of wire
2. a switch
3. a eyelet
4. 2 female spade connectors
5. a wire tap
First you need to remove your left side mid fairing to gain access to the fan relay. The relay is the black box, that is to the right and just below the fuse box with a 4 wire plug going into the bottom of it and thats all.
Next, out of the 4 wires leading into it, one will be green and yellow. This is the wire that trips the relay and turns the fans on. Take a piece of wire long enough to run from the green and yellow wire to where ever you want to mount your switch and use the wire clamp to clamp the wire for your switch to the green and yellow wire.
Now find a good ground. You can use any ground. I used the ground behind the windscreen that is for the instrument cluster. Run a piece of wire from the ground you chose to the location of the switch. Connect the wires to the switch with the 2 female spade connectors and your done.
Turn the key on and flip your switch on. The fans should come on.
Sorry for no pics. I did this today out of boredem. It turned out well though, so I decided to make a write up about it. Should be simple enough without pics though.
