Looking into wiring an aftermarket amp into the speaker wires for the trunk. Looked in the Service Manual and didn't find anything, also tried the search feature. I don't have an ohms testing meter and my method of using a standalone speaker wire and trying to match the connectors, where the trunk plug connects in under the left side panel, failed as well. I do however think that the most likely candidates are the pink and orange wires, paired with the same color wires that have a red stripe on them. The exact same matching wires come into the front fairing from underneath the tank, go through a connecting plug, and then into the stock radio/amp. Of course I'm speculating that these are the same wires since I can't trace them all the way under the tank and then through the massive wiring bundle. Was wondering if someone else has looked into or done this already and what the outcome was.
