Alps 8227L Wiring Guide

The generic Alps 8227L is a widely used platform for budget Android headunits. But finding the information on connecting the wires can be a challenge. We have compiled the ALPS 8227L Wiring Guide to help you with your installation.

Not limited to just the ALPS 8227L, these connectors can also be found on many of the YT9216, YT9217, and YT9218 head units and many others too.

Rear Connectors

There are several sockets on the rear of the ALPS 8227L units. This diagram shows the main connectors used. The socked marked ‘Power’ is usually the most significant problem as this has to interface with the existing vehicle wiring.

Power

Although labeled ‘POWER’ on the diagram, this connector carries not just the power (BATT+, ACC, and GND). It also carries all the speaker connections (listed individually here). Key1, Key2, ILL, and REVERSE all appear on the socket.

The connector plug looks like something just for the Android headunits; it is just a JVC/Kenwood 16-pin connector found on many of those early Japanese car stereos.

You can identify the socket for this 16-pin Kenwood plug by inspecting the socket on the 8227L. The Kenwood will have 16 pins in two rows.

In this diagram, you can see the 16-pin ALPS 8227L plug and its corresponding ISO plugs. A ready-built 8227L to ISO patch lead is available here and can save a lot of wire cutting and joining.

Pin 1 and Pin 2 are the larger of the eight pins on the 16-pin plug of the 8227L and various other Android headunits. Buying the correct adaptor for your vehicle is often much more straightforward than cutting and joining wires.

Other Connectors

All of the other connectors will have a plug supplied if they are enabled on the head unit. Not all functions and features are supported. You must confirm with the vendor which features you want to buy and that they can supply them.

USB1 and USB2 will both plug straight into the socket. If they don’t fit, you probably have the wrong plug on the USB connectors.

AV connector will connect to external displays for rear headrest screens.

Backup Camera is a short lead that will terminate in a yellow RCA socket.
