He never responded to posts after his success post, so we do not know what he did and what parts he really had. But, there are probably three possibilities to consider:

1. gibbo_ireland had a ULF all along (this does not do you any good)
2. The European GSM TCU requires a eject box to be connected, but not necessarily the pairing button (gibbo_ireland's use of the pairing button was merely coincidental after his eject box wiring modification)
3. The European GSM TCU requires the eject box pairing button to pair
