switch the wire going to the battery if you got red for positive put that wire on negative terminal and black ofcourse on positive terminal ..that should work..if your not using relay.. switch the socket from the ballast and just turn it around

Toyota headlamps use a ground switching system, this means that there is a common positive and when you switch from high to low the relay switches which side is grounded.
Other vehicles have a common ground and switch the positive side.
