I untaped everything, and it was an additional accessory I placed in line at the 12v constant side. I had a Kenwood 241 with a fuse holder in-line. My fault. My bad for wasting time and forum space with my personal ignorance of my configuration.

Ok, here are 3 images of the yellow battery wire in question.. It's spliced to to relay and to the scosche relay and the scosche stereo replacement module with door chimes.. Hopefully this will provide a bit more clarity.. I apologize for perhaps not being completely clear in my initial post. But again, I prefer providing all info in case I overlook or just miss something completely.

I was the installer. And It looks to be very much a part of the factory unit. I'll grab a pic here in just a minute! As for the complete detail in my first post, it's to provide as much background as absolutely possible so that I am able to give those that may be able to help all of the detail of my situation and everything I have tried or could think of to try. Pic will be available here briefly.

If it just needs to go to a 12 volt constant, then that's fine as long as someone can tell me the size fuse I would need since I can't find a fuse that went with the yellow battery wire.

Seriously? I am asking about the yellow wire labeled "BATTERY" from the harness. I didn't realize it was that difficult to understand my message. The yellow wire labeled battery appears to hold a fuse, and I have no other end, so I am asking if there is indeed another end or does that go to the battery side of an accessory such as the XM unit. Maybe that's a bit easier of a read. Perhaps pictures would have done more justice to the original post.

I removed my AVIC-Z110BT headunit quite some time ago because of battery drainage issues.I believe the issues were caused elsewhere, but I removed every aftermarket piece to ensure I could narrow things down. Since that time, I have moved from Cedar Rapids, IA back down to Georgia. Today, I went to reinstall the unit, and the Yellow "battery" connection, the fused connector, had no opposite end. So I noticed from my XM Pioneer unit that they plug together perfectly. I have a 2005 Chevy Trailblazer LS. Does the metra piece and relay and all of that mess take care of the battery side
