I installed it on my MT-03 2018 and as it turns out, it didn't work for its intended purpose.
I used it to take the USB power supply of the Key switch linkage, but the voltage of the power supply taken out does not become the state of charge even if I connect it with about 9V. attachment power supply, because the voltage may not be stable in the state of the circuit, I gave up the direct power supply and connected it to the circuit which supplies power directly from Battery. So I gave up on direct power supply and connected Relay's Switch as On/Off Switch to the circuit that supplies power directly from Battery, but it doesn't work. I tried various things, but I gave up using the power supply which I take out from this part as a conclusion, and was able to get expected operation by taking out Attachment power supply from another part and connecting it to Switch of Relay.
It is attractive that the power supply can be taken only by interrupting Cabrau, but because the power supply which can be taken out seems not to be stable, I think that it is necessary to choose the use and to use it.
In addition, because the polarity of the power supply taken out is opposite to the color of the Cable in MT-03, and Earth seems to come to the Red wire and Attachment to the Black wire, I recommend that you use it after confirming it with Tester etc. when you use it though there was it in other reviews.
