i bought a scosche FAI-3A output converter so i can hook up a system with my stock radio, and am wondering how to wire it into the system....i know im to splice the speaker wire into the top ports A1-A8, but i don't know where im to hook up the remote wire to the amp. is there a wire on the cars harness or is it on the output converter? if anyone has experience with this module, what is the wire coming out of the lower lefthand side? im guessingground, but the booklet doesn't say. thank you!
