How to Add Second 4-Pole Trailer Connector to 2015 Ford F-150

Updated 04/28/2016 | Published 04/24/2016

Question:

I have a 2015 Ford F150. I have both the 4 and 7 prong outlets on the back of my truck. I want to tie my tool box lighting into the 4 prong wiring. Is there a plug and play harness available to tap into my vehicle wiring? Thanks...

If you want to add a separate 4-pole connector to your F-150 to power the lights in your tool box you can use part # 118384. This will simply plug in behind your existing trailer connector, going inline with it. Your existing 4-pole/7-way will remain active but you'll then have a second separate 4-pole for connection to the tool box lighting.

If your tool box uses different wiring/connectors than a standard 4-pole, please let me know.

You'll want to ensure the total load from all lights does not exceed the current capacity of the wiring harness.
