It looks like the wiring harnesses are fairly standardised with only the

The devil is in the detail! The connector may actually be the same but
which wire to which pin, whether wires are linked, and what is earthed may

be critically different. At least one radio manufacturer offers adaptors

boards to let you link your existing harness to his new generation 8.33
radios.
