Question:
Hi, do you have a trailer wiring harness install video for a 2018 Acura TLX? I recently installed the trailer hitch and would like to now add the brake/turn signals. Hopefully you can assist. Thank you very much.

Hey David, thanks for reaching out!
We don't currently have an installation video of any trailer wiring kits on a 2018 Acura TLX. With that being said, I recommend picking up the T-One Vehicle Wiring Harness # 118697 because it tees in behind your tail lights and draws power directly from the battery via a designated wire.
For someone who's new to wiring you can count on it taking about an hour, but if you're familiar with wiring you'll be looking at about 30 minutes. If this is completely out of your element, I'm also linking our installer locator tool that you can use to find shops in your area who are willing and able to do the installation for you.
Do you normally tackle DIY projects?

Hey David, did you decide to try installing the wiring harness yourself, or did you find a local shop to help out? I'm curious to know how it went for you, as it could help others who are considering a similar project.
