What's important to note, the 5 amp fuses within the TCU, part of the relay package is NOT part of the ignition. When you turn your ignition on, that wakes up the transmission so if your not getting power to the ignition(I think you said you were getting power)than that would be a separate ignition fuse. As I previously stated, I thought the ignition may have been my issue and I replaced it but it wasn't. You should be able to hear the relays click in the TCU when the ignition comes on. As I mentioned in my private message, my TCU was located with my ECU but others can be located on the transmission itself(the housing).
