The 750SS ie uses a 1.5M ECU, the 620 uses a 5.9 ECU
The 1.5m has a single multi pin connector where as the 5.9M ECU uses two connectors.
As standard the 620 ECU is coded to the Clocks with the Clocks in turn coded to the transponder in the key
As such the looms are very different, even the 750/900SSie had different looms, the earlier one had the fuse box on the fairing bracket the later ones had it next to the battery under the tank, which I have found a lot better for using as a race harness.
This throws another difference into the Mix. The earlier bikes use a A0 version of the 1.5M ECU where as the later bikes/harness uses the A8 version. Main differnce between the A0 and A8 versions of the 1.5M ECU is the way they are interlocked, so can't be swapped from early to late loom and vice versa.
Speaking of 750SSie's and as its sunny out I think I'll take mine for run over to H-Cafe and see who else is out on their bikes today
