Had to wait a bit longer than expected for shipping, but once it arrived, the Navitas TSX harness was exactly what I needed for my EZGO. It connects seamlessly to the 1268-1264 controller, and now my cart feels more responsive. Just wish the instructions were a bit clearer, but overall a solid product.

I’m super happy with this vehicle harness for my EZGO. The Navitas TSX is top quality, and installation was a breeze. My golf cart’s performance noticeably improved, and I’m getting more consistent power output with the 1268-1264 controller. Plus, shipping was quick – arrived within a few days!

Perfect fit for my EZGO with the 1268-1264 controller! The Navitas TSX harness arrived on time, and it was easy to install. I’ve been running it for a few weeks now with zero issues. My cart’s speed and torque have improved, and it feels more reliable overall. Highly recommend this harness.

The harness fits well and is built tough. It matched up with the 1268-1264 controller on my EZGO without a hitch. I did have a small issue with one of the connectors being a bit tight, but it wasn’t a dealbreaker. Worth the upgrade if you’re looking to improve your cart’s performance.

The harness itself is solid, but the delivery was delayed, which was frustrating. Once I got it, the install was fine, and it connected right up to my 1268-1264 controller. Not sure if it’s giving me the performance boost I expected, though – might need to fine-tune some settings.

The harness works fine, but I had trouble getting one of the connectors to snap in securely. It’s functioning now, but the fit wasn’t as perfect as I hoped. Still, I noticed a slight improvement in performance with the 1268-1264 controller on my EZGO.

This Navitas TSX harness exceeded my expectations. It’s durable and connects perfectly to my 1268-1264 controller. My EZGO has more power and accelerates smoother than before. Install instructions were decent, and the whole process was hassle-free. Would buy again for sure.

Quick delivery, but the packaging could’ve been better. The harness itself is solid and was an easy plug-and-play with my EZGO 1268-1264 controller. I’m still testing it out, but so far the performance boost is noticeable. Wish it came with better documentation, though

This Navitas harness made installing a TSX controller in my EZGO with a 1268 controller simple. Everything lined up perfectly—no splicing or guesswork needed.
Terry H. –
Solid OEM-style replacement. Hooked right into my 1264 Curtis controller setup. Would’ve been nice if wire labels were clearer, but still easy enough to follow.
Brent G. –
Harness works but had a few loose pins I had to reseat. Once secured, everything functioned as expected with my 48V EZGO TXT.
John T. –
Best price I found online and it shipped fast. Used it for a 1268 controller swap and the fit was perfect. Definitely recommend for TSX conversions.
Kyle W. –
Anyone know if this works with both 36V and 48V EZGO models? Installed it on my 48V TXT and it works great so far.
Bryan L. –
Clean install, OEM look, and no wire trimming. The Navitas TSX harness is a must if you’re upgrading an EZGO with a 1264 or 1268 controller.

Had a delay with UPS losing my package, but Prime Golf Parts sent a replacement fast. Harness is working great now with my 1268R.
Ethan R. –
This made my controller upgrade smooth and stress-free. Plug-and-play into my 2008 EZGO with a Curtis 1268. Great product!
Luke H. –
Had to reposition a few wires to get better routing, but everything fit perfectly with the TSX and 1264 setup. Cart runs better than ever.
Carl H. –
Love how everything just connects—no soldering or splicing required. My EZGO with the 1268 controller is back in action and running strong.
George S. –
Solid replacement. Installed with a TSX 3.0 controller and 1264 Curtis controller—everything powered on and worked first try.
Finn K. –
Upgraded a customer’s 2007 EZGO with this harness and a Navitas controller. Great fit, no hassle, very clean install. Makes tech work easy.
Anthony R. –
Is there a version of this harness for TXT Freedom models? This one worked great for my base model, but just checking compatibility for another cart.
Adam P. –
EZGO + TSX + this harness = smooth power delivery. Works great with my 48V system. No regrets.
Morgan V. –
Good quality harness, wires are thick and durable. Matched my 1268 Curtis controller pins exactly. Would buy again.
Leo R. –
Used it for a golf course fleet conversion—plug-and-play with all 1264-equipped carts. Huge time-saver.
Dan L. –
This harness made the Navitas install so much easier. Great solution for anyone upgrading their EZGO with a 1268 controller. Just plug in and go.
