It's not the cheapest, but I think I have found my solution as climate control and outside temperature info is what I care about the most.

Hi there,
I am installing an aftermarket head unit in my 2005 Mazda 3 (climate control), but it appears that I have no separate harness for the LCD, since mine is plugged in the factory head unit.
I couldn't find a separate harness for the LCD in my dashboard, so does this irrevocable mean...
