04 hybrid Civic 4 door. Worked fine. Installed amp, spliced a power wire from a tail light (orange and yellow I think) and ran it to the amp just for remote turn on. Done this in the past with other vehicles without issue. And indeed it worked fine for several months. Now suddenly no tail lights, no front sidemarker lights, no dome, map lights etc.... All appears to be from the #3 "small light" fuse circuit in the under hood dash, but it is good and has power on both sides with no voltage drop. A bit at a loss what to check next, tail light relay does not click. Cannot find wiring diagram for what I need online. Any ideas?
