Where Does a Brake Controller Plug Into on a 1999 Ford F-150
Updated 02/08/2016 | Published 02/07/2016 >
Question:
There is 2 grey plugs under my dash. A small one by the emergency brake, and a large one by the diagnostic port. Is the larger plug a port to hook up a plug and play electric brake control, such as #3034-p? Please give your advice. I hate to buy, and then have to send back.

On your 1999 Ford F-150 with factory 4-Way flat, the brake controller port is located under the dash close to the center console. It is near the OBDII diagnostic port. I have included a link to a video showing installation of a brake controller that shows this location. Your truck uses harness # 3035-P and not # 3034-P.
You will also need to add a 7-Way connector. For that I recommend # 118242 which also includes the relays and fuses to make the harness functional. You might want to check ahead of time to make sure the fuse and relay locations have the metal contacts inside because there have been cases where the locations where there but the ports of the relays where just dummy ports that did not work. I have linked a video for this harness as well.
