I have had no luck seeing schematics. I see connectors with most showing pin outs and general locations of the routing of the harnesses. Which I find to be basically useless when it comes to troubleshooting. I have a fuse blowing out on the dash fuse panel for the RH rear tail light and with the fuse out, I still show a short on the hot wire at the tail light connector. Without a schematic, I have no idea exactly where the wire routes through to get to the fuse panel. So I took it into the dealer, two days later and they seem clueless. I wish I could see a schematic and fix it.
