Does The TowSmart 4-Wire Harness Have A Single Or Dual Ground Wire?

Updated 09/19/2025 | Published 09/12/2025

Question:

The description states there are dual ground wires, but the photos only show one ground wire. Does it, in fact, have dual full length ground wires? Thank You Mitchell Saad

Hey Mitchell,

That wiring harness # TS67RR is in fact a single full length ground wire, not dual. I will get that updated on our page. I did not see a dual ground wire harness on our site. I apologize for that confusion, but it is a single ground wire unit.

What kind of trailer are you replacing this on?

Thanks for your reply. I did in fact find a dual ground wire trailer wiring set on your website. As a matter fact, I just ordered one yesterday or day before. It’s called a wishbone. I’m replacing the wiring on a 6 1/2 x 12‘ utility trailer.

@MitchellS I do see that one now, for some reason it was not populating for me haha. I am glad you found one and got it ordered. You'll have to let me know how the install goes.
