Hey all,
I'm doing a custom install of a waterproof USB charger and voltmeter unit in the glove box of my 2015 GTX 155 (has separate + and - wiring for each). I'm after a wiring diagram for the gauge cluster, so I can slice off and use some of those wires rather than running new wiring from fuse box/battery. I've found 12V + and - on the plug that goes into the rear of the gauge cluster, so figured I will run power from that to the USB charger since it's only going to be drawing power when I plug my phone into it. However with the voltmeter, I only want it to wire it up so it only shows voltage when the DESS key is plugged in (and/or power button is on) but I'm struggling to find the wires to use only when the power is on. Any ideas?
Cheers
