Greetings, All! New to the forum here and have a dilemma. I bought 2 after market Gentex rear view mirror knockoffs for my 05 Accord EX V6 and my wife's 06 Civic EX. They have temperature and UV sensors that need to be wired through the firewall. The instructions simply say to run the wire through the main firewall grommet. Well, that looks like climbing Everest. Any hints? I've already browsed the threads on this issue and they all relate to Honda OEM mirrors that don't have to be fed through the firewall. Your help is most appreciated!
