Question:

What do I have to do to wire led back up lights. When truck is in reverse i still only have my constant hot and running lights. What do I hook in in the trailor so they only come on when I reverse?

Expert Reply:

The center pin on the 7-way trailer connector carries the reverse lamp signal. Install your reverse lamps such as # BUL10CB as well as the # A45CB pigtail and the # A70GB grommet and # BK70BB bracket if needed.

Then, run a length of # DW02359-1 16 gauge wire from the center pin on the trailer connector back to the running lights.
