good afternoon, this morning I got ready to install the on-board computer, which did not come with a pre-installation, and I had to do the installation in this way: pin 3 white CAN-Bus H

pin 4 green CAN bus L

(The can bus H and L took it from the hose next to the dashboard)

pin 6 tan ground

pin 7 red constant +12V fuse 13 (circuit 30)

pin 8 on light blue +12V fuse 10

but it doesn't work, it doesn't turn on, it doesn't do anything at all, have I done something wrong?
thank you
