I've been looking into wiring a manual fan override. It increase engine life and performance by keeping your engine cool. Has anyone else done this? Any advice?

From what I've read on various forums some say just a switch into the existing relay is sufficient. Others say it's better to use an additional relay in parrallel. The reason being is it could interfere with the sensors and throw codes on your ECU.

I found an expensive all inclusive kit at XS Boost Performance and a write-up at R1 on how to do yourself with AutoZone parts. I think I'll opt for the latter and save money for another upgrade.

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.

Thanks... great write-up by the way. Hopefully it'll translate well to the R1. Although I believe my fuse box and relays are located on the left side behind the fairing panels.

If you're talking about a clamp-on wire tap (splice) then I'd suggest a more sealed connection. Take the time to solder and seal the wire or something similar. 99% of the time the clamp tap will be good enough but inevitably that one water drop will find its way in down the road. Bike electricals aren't impervious (far from it) but while you're in there you might as well protect what system integrity is already there.

yea, im not really a fan of any kind of crimp connectors or taps..
solder/heatshrink EVERYTHING... and if you dont have to, dont cut the stock wires..

Me either... the previous owner of my bike used wire taps on my side markers rather than reuse the OEM quick release wire harness!!! :wall:

So I have some ghetto electrical to rectify on my bike.
