Repairing Trailer Light Wiring That Were Cut

Updated 10/15/2025 | Published 04/28/2023

Question:

Our trailer lights got cut. Do I connect them individually yellow to yellow and brown to brown or can I twist them together and then connect them?

If the wire was cut you should be able to splice the similar colored ends together. I recommend using Heat Shrink Butt Connectors # DW05744-10 to ensure you get a strong connection and it keeps moisture out of the connection.

@JosephB Yes, we do. Take a look at the video in the link i provided. If you fast forward to around the 4:50 mark you can see Ryan using one of the butt connectors.
