Honda 4 Pin To USB 2.0 LVDS Cable

Honda vehicles use a proprietary 4 pin dash connector to route USB data and LVDS video and audio signals between the factory head unit and the dashboard harness, CarPlay and Android-Auto ports, and rear displays. When owners swap the factory radio for an aftermarket Android head unit, add a CarPlay box, or relocate the USB port, the factory 4 pin socket does not mate with a standard USB A plug, so they need an adapter.

This harness is that adapter. One end is the Honda 4-pin female socket, a TAK aftermarket replacement matching the factory housing and lock. The other end breaks out to a standard USB 2.0 Type A connector, either male or female, or stays as a second Honda 4-pin female for extending the factory loom. Because this is a signal and LVDS video line rather than a high speed Ethernet coax, the copper-core cable is built to carry USB 2.0 data plus 5 V power and analog LVDS audio-video without losing the screen signal.

Whether you are swapping a Honda factory radio for an aftermarket Android head unit, adding a CarPlay or Android-Auto USB port to the dash, or extending the factory 4-pin signal loom to a new screen, this harness gives you a plug-in adapter between the Honda 4-pin socket and a standard USB-A end. Pick the gender that matches your install.

Available Configurations

Honda 4 Pin Female to Honda 4-Pin Female

Both ends are the same black Honda 4-pin female socket with the factory-style locking latch. It is a straight, shape-to-shape extension of the factory loom, with no adapter in between. The copper core cable runs continuously from one 4-pin socket to the other, so every pin on the factory connector maps straight through to the matching pin on the other side.

Use it when the new head unit sits further back in the dash, when relocating the radio to a deeper pocket or a trunk mounted box, or when the factory pigtail is simply too short to reach the new mounting position. Because the LVDS video and USB signals pass through a factory-matched connector rather than a hand-spliced joint, the screen image and USB data stay intact. The molded strain relief at each socket is built to survive dashboard heat cycles and vibration, and the 0.5 m to 3 m length range covers everything from a tight behind dash jump to a center-console-to-trunk run.

Honda 4 Pin Female to USB 2.0 Type A Female

The Honda-side end is the factory 4-pin female socket. The device side end breaks out to a standard USB 2.0 Type A female receptacle in black plastic. The Honda 4 pin end clicks into the factory loom, and the USB-A female presents a standard, familiar dashboard port, the same shape as any USB flash-drive socket.

It is the go-to choice when you want to add a working USB port in the dash. A USB flash drive, a CarPlay or Android Auto dongle, or a phone charging lead plugs straight into the Type A socket, while the Honda 4 pin female stays mated to the factory harness. No dash trim modification is needed beyond a standard USB flush mount hole. The copper core carries both the USB 2.0 data lines and the 5 V power feed, so the port actually charges and syncs instead of only passing a video signal.

Honda 4 Pin Female to USB 2.0 Type A Male

The Honda-side end is the factory 4 pin female socket. The device side end breaks out to a standard USB 2.0 Type A male plug with the familiar USB logo molding and strain relief. The 4 pin female clicks into the factory dash loom, and the USB A male presents a standard plug ready to seat into any USB A port.

It is the direct plug-and-play link for an aftermarket Android head unit. The USB-A male plugs straight into the new head unit USB A port, keeping the factory USB and CarPlay function alive after a radio swap without cutting the factory harness. The molded plug is sized for repeated plug and unplug on the bench and in the customer car, and the copper core carries the USB 2.0 data and 5V power end to end, so the new head unit recognizes the phone, the CarPlay dongle and the flash drive the same way the factory radio did.

Applications 

Closing line: because the Honda 4 pin socket carries the factory lock and the copper core is matched to the LVDS and USB signal, the install stays plug-and-play. The video and USB data survive the head-unit swap instead of degrading through a hand-spliced joint.

Product FAQ

Q1: Which length should I order?

0.5 m to 1 m for behind-the-dash head-unit swaps, 1.5 m to 2 m for center console to head-unit runs, 3 m for trunk-mounted head units or rear-seat screen routing. When in doubt, take the next length up.

Q2: Is this a genuine Honda part?

No. It is an aftermarket TAK replacement built to mate with the Honda factory 4 pin socket. It is not OEM Honda. It is designed as a cost-effective retrofit and extension cable for head-unit swaps and USB upgrades.

Q3: Does this carry LVDS video or USB data?

Both. The Honda 4-pin factory harness routes USB 2.0 data plus 5 V power and LVDS video and audio between the head unit and the dash ports and screens. This harness carries those same signals. The copper core is sized for USB 2.0 and the LVDS video link.

Q4:Can you make a custom length or a non-standard pinout?

Yes. Every harness is built to order. Custom lengths, other end connectors and custom pinouts are quoted on request. Send us your factory connector photo and the wiring diagram showing which pins are USB 5 V, D plus, D minus, or LVDS, and we will terminate to your spec.
