04 yz 450f thermo switch

I am new to the yz450f and just wondering where this wire should go mine just goes over the top of the radiator


That's not stock.  The hose has been cut to splice it into the system, and it most likely belongs to a trail computer thing that had a temp gauge.  Replace the hose and discard it.

Would it hurt anything leaving it in as I am planning on getting a trail tech in the near future
