This worked great for a 2005 Chevy Express 2500 van. It was an extremely simple installation that fit perfectly with the factory light connections. The wiring was the perfect length and there were zero issues. Definitely recommend!

As simple as it could be.

Worked fine on the application stated.

No wire splicing needed and easy to install. fit perfect on my 2022 GMC Savana

Easy to install

It was very easy to install and it fit like a glove. I used it for my 2004 Chevy express

I drive a cargo van. I also live in it. The Curt harness was easy to plug in. One side plugs in on the driver's side rear (behind my bed) and the other on the passenger's side near that taillight. Thankfully, when building out this van, I'd thought ahead and left the connectors easy to access. It's that easy. Unplug the respective connector, plug in the harness. Repeat for the other side of the van. (Hook up a ground wire, too, using an existing screw). If you drive a Chevy or GMC van, I would recommend this purchase. Curt makes good products. This one was affordable and simple. As for the guy who had a short develop, it makes me wonder what he did wrong. This harness is so simple, I cannot see how a person could have a problem. One last thing... The shipping was super fast, too!

Produit conforme et de bonne facture. Installation rapide sans aucune complication sur mon véhicule. Le connecteur 4 broches est solide et bien protégé. Je recommande vivement la marque CURT pour le remorquage.

I tried to use taps and wires to connect to the existing harness in my 2021 Chevy Express van, and after spending $30 on bits and bobs and dicking around for three plus hours trying to get it to work, I gave up and bought this. I unplugged the connectors to the tail lights, plugged in the adapter pieces, routed the wire and was done in 45 minutes. The lights worked perfectly.

Simple and easy to install

Had an issue with a broken plug but they replaced it in one day

Install this trailer wiring harness on my 06 Gmc Savana van , hooked right up to the rear tail light harness on either tailight plug and play , just had to tuck it all in neatly into the roof zip ties included
