For every one thats going to put a tether switch on their ds450 be very very careful where you go hook it. Brought my ds into the dealer ship for the engine light comming on and. I get a phone call today saying my computer is fried in my quad that is one phone call i never need. The dealer said it would cost close to $1500 to get a new computer. So any buddy looking to put a teather switch make sure you do it right. And dont let friends do it i found it.
