Question:
I have a 2023 Jeep gladiator sport S with max tow. Curt makes a spectrum brake controller that looks like a nice option. But there are a lot of different part numbers on your site for this. Trying to find out which one works with my jeep and any additional harnesses that may be needed for this to be installed. Thanks

Hey Ed, for your 2023 Jeep Gladiator it looks like you'll just want the Curt Spectrum Trailer Brake Controller # C51170. This is going to include the Spectrum brake controller, plus the wiring harness # C55FR.
If there is anything else you need help with, feel free to leave a comment and I'd be happy to help!
