Although the wiring of the MR2 stereo systems has undergone many changes over the years, it can be difficult to figure out how to wire the stereo correctly. To help make things easier, it is recommended to find a diagram of the wiring for the particular year of the MR2 that you’re working with.

Understanding the wiring diagram can also provide helpful hints on how to upgrade or modify the original stereo system.



Understanding the Wiring System of the MR2 Stereo


The wiring diagram for the Mr2 stereo system is fairly complicated, but ultimately it all connects to the main wiring loom. This is where all the different components get their power. The loom typically consists of two 12-volt constant power wires, two 12-volt switched power wires, one ground wire, one antenna wire, and two speaker output wires. All of these wires are connected to the main wiring loom, but may have additional connections that lead to other components.

It is important to know which wires connect to each component and where they should go in order to ensure that everything works properly. You’ll also need to know how to use the necessary tools such as crimpers, strippers, and heat shrink tubing to make sure all the connections are secure. Understanding the wiring system can also help you troubleshoot any problems that may arise with the stereo system.
