I just bought an 04 Accord, and there is an issue.
it had an Alpine head unit installed, in the lower dash cubby (underneath the the factory radio) which I upgraded to a Bluetooth head unit. Anyway the accent lighting to the factory radio, and the heater vent settings does not work. I have to turn on my dome light to select the different vent settings.
I noticed there is an orange wire hanging from the back of the factory radio that is not hooked up to anything. Where does this dimmer wire go?
im pretty sure this is the problem, but I can’t see much.
