I am rewiring the Bose System in an 89 Accord SE-i because the amp blew the speakers. I'm putting new speakers in and deleting the amp because it has an after market headunit with 4x35 power. How can I figure out what wire goes where out of the factory harness? I don't want to re-run wires, I'd like to use the factory wires, I just want to know what wires run to what speakers out of the harness that went into the factory amp, and what wires are for what on the harness that connected into the factory stereo. Thanks
