Install Plug for Trailer Lights [Step by Step]

What's better than fixing your trailer? A spare car key without leaving home! I started Tom's Key Company (tomskey.com/?Tomah...) so you can get quick and affordable DIY spare car keys and fobs shipped to your front door.
Installing a plug for trailer lights can be done with a little work and some basic tools. Pick up a universal trailer wiring harness on Amazon USA: amzn.to/2KOsRJ8

For vehicles that did not come with a hitch but have had one added, having a wiring harness is essential so you can safely tow a trailer. Be careful to only tow trailers and loads appropriate for your vehicle. A car, minivan, or small SUV will have very different towing capacities from a large truck. This video demonstrates on a 2016 Toyota Sienna. Wiring will be similar for many other vehicles.

This installation took several hours between removing trim panels, fishing wire through hidden spots, etc. One area that time could be saved is not figuring out which existing vehicle wires work the brakes and turn signals. That would avoid needing to splice wires. Rather, there are kits available that have plugs already configured specific for your vehicle and essentially avoid the splice. Check out the CURT brand kits - it costs a bit extra, but saves quite a bit of time.
Much faster - use a vehicle specific CURT 4-pin trailer wiring harness kit

No running lights?

[@lawrencethurston1960]

Question where do I run my wire for the running lights so I can have running light for dark

[@MakinMoneyISeasy]

Same problem I am having now. Did you find a solution? I'm thinking I might need to run new wires to the battery with a switch...

[@costiq4048]

That’s what the brown wire is for

[@QBAN_BOY]

​@@MakinMoneyISeasy I have the same problem

[@agriffin_03]

i’m stuck on the part where the Turn Signals and Brake Lights use the same wire cause if i wire the brakes and turn signals into the same plug on the trailer light connector, the brake lights will flash with the signals

[@tommylong2151]

Did you ever figure it out, currently having this problem
