I did not change my connector...if you align the locking tab ,it will plug in and work.I have made an adapter for my 8 pin cable down to 6 pin ,and it also works on 6 and 8 pin radios using the 6 pin adapter.
if you insert your 6 pin cable into an 8 pin plug and skip the 2 outside pins it will be correct.

Those two pinouts are the same minus the wire on the end (I don't have terminal functions in front of me)...I too use the 6 pin and 8 pin interchangeably...mostly on x80/x180 but I grab whichever one my hand lands on first
