2016–2022 Honda Civic 5" to 7" Touchscreen Radio Upgrade – Plug & Play Wiring Harness

Tired of the small screen in your Civic LX or Sport?

Your car's 5-inch radio was designed to be upgraded. Honda's OEM 7-inch touchscreen head unit - the same one found in EX, EX-T, and Touring trims - drops right into your dash. The only thing standing between you and a bigger, better screen is the wiring. That's exactly what this harness solves.

No cutting. No soldering. No crimping. Just plug it in, follow the instructions, and enjoy your new touchscreen.

What's Included

• Main wiring harness
• AM/FM Tuner to Antenna Cable
• AM/FM Tuner to Headunit Cable
• GPS Antenna
• Reverse Camera Wire

Everything you need to complete the wiring side of the upgrade — in one kit.

Why This Harness?

It's the only plug-and-play solution built specifically for the OEM 5" → 7" upgrade.

Other wiring harnesses on Amazon and eBay are designed for aftermarket (Android) radios. This one is purpose-built for installing the factory Honda 7-inch touchscreen — preserving your OEM look, backup camera, AM/FM radio, GPS, and CarPlay.

• Fully plug-and-play — connects directly to your car's existing connectors
• Fully reversible — want to go back to stock? No problem
• No special skills needed — if you can use a screwdriver, you can do this install

Head Unit You'll Need

This harness works with the OEM Honda 7-inch touchscreen head unit. When sourcing your head unit, look for part numbers in the 39101-TBA-Axx family. Make sure the unit you purchase includes a built-in amplifier — units without one will produce no audio output.

For the AM/FM tuner module, look for part number 39800-TBA-A21 (available on eBay).

Head units are commonly found on eBay. Any 10th gen Civic 7" screen will work, whether it has physical volume buttons or is fully touch — your choice.

Frequently Asked Questions

Will this work with my 2016, 2017, 2018, 2019, 2020, 2021, or 2022 Civic?
Yes — this harness is compatible with all 2016–2022 Civic LX and Sport trims equipped with the stock 5-inch head unit. This includes all model years across LX, Sport, EX, and EX-T trims — whether you're doing a 2017 Civic EX radio swap, a 2019 Civic LX radio upgrade, or a 2021 Civic Sport radio swap.

Do I need to cut any wires?
No. This is a true plug-and-play harness. It connects directly to your car's existing connectors with no cutting or soldering required.

What head unit do I need to buy?
You'll need a Honda OEM 7-inch touchscreen head unit from the 39101-TBA-Axx family. These are widely available on eBay, typically for $100–$300 depending on condition.

Will my backup camera still work?

Is this reversible?
Completely. The harness installs between your car's existing wiring and the new head unit, so removing it returns your vehicle to stock condition.

Will my AM/FM radio, CarPlay, and GPS still work?
Yes — as long as you source the AM/FM tuner module (part # 39800-TBA-A21) and use the included GPS antenna and cable.

Looking for a 10th gen Civic plug-and-play radio upgrade harness that works with the OEM head unit — not an Android radio? You've found it.
