New head unit issue

Had a new head unit installed in my 94 Ex now my dash lights are on anytime the truck is running, Has anyone seen this before? I have no idea what is causing this and its annoying the hell out of me. TIA

Sounds like they wired the illumination wire to a power source, sending voltage back to the illumination circuit from the radio, instead of the opposite.

Check the wiring of the illumination wire, or take it back to where you got it installed and ask them what the hell they did.

Thanks DjDom, I will check the wiring this weekend.

No problem.

I bet you accidentally have the orange wires from the car side of the harness connected together.
