Audio Problems

Been working on this 2001 RSV. The bike was dumped and had damage to the lower cowling that holds the fuses. The Main Control Unit was also damaged. The Audio doesn't work. I replaced the MCU (used, they said it worked), put dielectric on all connections. Did a DC volt test and I am getting power up to the audio fuse in the lower cowling. There is no power in the 18 pin connector that attaches to the radio. Are there any other fuses I should be looking for? Any suggestions?
