I am installing ttt mirrors on my truck. I have the lighted ones and the instructions say to use 14ga wire, and attach to the light switch box. Useing the brown with white trace wire. My question is what is the best way to connect these wires? 14ga wire seems to big to get 2 of them in this small area. Has anyone installed these? Any help would be appreciated. I was going to just cut the brown white trace wire and splice them together. Is there a cleaner way to do this?
