Brake and Turn Signals Not Working on a Trailer Towed by a 2007 Saturn Outlook

Question:

Hello and good day. Sir perhaps you may be able to help. I have a Saturn 07 Outlook. It has the factory round 4 pole plug under the bumper by the hitch. I have part 118384. I checked the terminal position on it and it matches the factory plug positions. It goes to a flat four pole connector which connects to my trailer. It is a single wide tilt Karavan. I have running lights but no brake or turn lights. Any suggestions?

Even if your 2007 Saturn Outlook has the same connector that goes with # 118384 it is possible that the connection on the vehicle is not fully functional. The vehicle would have to have come from the factory with a 7-Way trailer connector for # 118384 to work properly.

What you need is the T1 harness, # 118434 that you referenced. This harness plugs in line with each of the tail lights and provides a 4-Way trailer connector. I have included a link to the installation details and a link to a video showing a typical installation for you.

If your Outlook did come with the factory tow package that included a 7-Way trailer connector, there could be some fuses and or relays that are missing or need to be replaced. Consult the vehicle owners manual to determine the location of the fuses/or relays to check on them.
