Expert Reply:
I can help you wire the Replacement Tekonsha Trailer Breakaway Switch # 420000 and the accompanying diagram shows exactly how it will be wired; I have also added a link to a video which shows it being installed. The white wire is a ground wire and the other two wires are interchangeable.
One will be spliced from the from the switch and blue trailer brake wire that is running from the trailer connector to the trailer brakes. The other wire will be spliced to the blue brake wire coming out of the breakaway box.
I have also added a link for you to a help article on breakaway kit installs which has these details.
