The issues I'm having is that my HU works, but now my rear defogger and tail lights don't work.
I was able to identify the vehicle wires, but what wires do I connect them to coming off my HU?
Also right next the dark green wire for my defogger is another black wire, what do I connect that to? Do I assume it's a ground and just run it to some metal in my car?
Thanks for the help yall!
