Question:

I need to replace the axles and the wiring for the brakes on my enclosed car hauler. I need 3 of these 7K drop axles as I was able to verify the measurements you guys have on your site (thank you!) but what wiring do I need?

Thanks for reaching out, and I'm glad you were able to determine fitment of the 7K etrailer Drop Axle # e85SR for your car hauler trailer!

The wiring you need to connect all of your electric brakes up to your trailer is 10 gauge wire which we sell by the foot as part # 10-1-1. I also recommend picking up heat shrink butt connectors like part # DW05745-10 to protect your wiring connections from the elements.

If you aren't familiar with how to run your brake wiring I'm adding a photo for you to get a visual. I'm also attaching some review videos for you to check out!
