Trailtech temp gauge to turn fan on

I installed a switch into my bike to turn the fan on manually. The fan will also go on when it reaches the set factory temperature. Now my fan can go on and off with. O key in the ignition. But all that work to wire the bike up and cut into plastic to install the switch is annoying.

I found this one post from 2018 where someone else was talking about installing a switch to turn their fan on manually. And on that post someone posted a company called trailtech that made a fan and gauge kit. You would mount the LCD gauge to your radiator. Then wire it into your fan. Set the temperature you want the fan to go on and thats that. But the fan which comes with the kit wouldn't fit our bikes. The kit retails for like $279. The member who posted about trailtech said that if you got in touch with trailtech they know about our bikes and they would sell what we needed without the fan. Here is a link to the part needed for our bikes. And it costs $59. This looks like a much better option than cutting into our plastics to install a switch and then wiring the bike up.

I cut into the black plastic airducts and put a red light oush button switch so I could easily press the button. Looks like a nuclear launch button lol
 
SickDuc i recieved an email from Trailtech. There is one more item needed from them. Its their temp sensor. Here is what he wrote me.

"The customer would also need one of our temp sensors as the meter has to be able to measure the temp in some way. You could mount the meter where every the customer would like. It does not have to be mounted to the radiator. There are three leads out of the meter. One is power in, one is power out to the fan, and the other is for the temp sensor.



You could use the meter to control a fan on any bike. You just have to have DC power and a temp sensor for measuring the temp. Keep in mind that our controller is only designed to run our 4” fan which is only a 30watt draw. If you are using it on a fan with a higher wattage draw it my not work."
 
The Panigale OEM Fan is larger and will draw more than 30 Watts. My guess is 50-70 Watts. Be careful running a parallel circuit to the fan: when you power the fan you will also back flow power to the BBS. If you key off the bike and flip the fan switch, you will power up bike (dash will come on, etc.) Need to wire in a few diodes.

I went through a similar process when wiring a Scorpio Alarm and opting to make a custom wiring harness to include flashing indicators when the alarm is armed, disarmed, triggered.

Is there anyway to make this work? Or is this a dead issue if the fan is 50-70 watts?
