Trying to install Roadmaster brake-lite relay 88400. Per Roadmaster instructions need to id which of 3 wires is the "cold" one to tie into on the brake light switch. The switch has 3 wires out the top. None of three showed voltage. I am not sure what they mean by "cold" one? The instructions have many warnings of damage if I choose wrong one. Any help would be appreciated. Thanks
