I have repinned the tcu connector to a new 26pin combox connector, I have used both pin 17 and pin 36 from 54pin housing. My issue is that pin 17 has no power at all, I have looked at the fuse box in glove compartment and the fuses relating to Bluetooth telephone all have the correct fuses in place
