Thanks Buffalo & Dave for the info.
Just my luck, I was behind the glove box changing out the cabin air filter last week too.
I'm trying to track down the "e-gremlin" causing my radio/instrument gauge to go in/out randomly. Since I changed out all the fuses related to the radio and instrument gauge and there is no specific event(s) (ie. bump, speed, night/day, accel/decl, or kind of beer I'm drinking..just kidding on this one) that cause the problem, I would like to find the location of the ground (G503) that is common to those components. I hate electrical problems (used to it on BMWs & Mercedes, never expect it with a Honda).
The link to the forums' Electrical Troubleshooting manual doesn't allow me access to everything. I can open the fuse/relay link and menu. That's about it. All other links say access is not allowed.
