OK I need to do some work now (pesky job) but look here. Search for U407. There is the various sockets for the BITII 54 pin version. Have a check and compare with your setup. Compare and contrast with Io1157 Telematics control unit. You may want to start cutting and pasting some of those tables (green table looking icon) into excel with notes on what unit they came from, as it may assist you when you come to swapping pins around. It's a lot of pins to remember.
