don't cut it .......the viper gauge need the signal too ....u need to send the signal to the cdi and one to the cluster ..
your suppose to hook up on the blue/red at the temp sensor wire not on the black wire at the temp sensor ...and bring that wire to cdi ....if u connect the black wire to cdi you ground the cdi so he will think it overheat....u almost got it u just took the wrong wire
