Help with power supply change.

Hi are all scorpion4 power supplies compatable?
I'm looking at replacing a-

Sanken Gsk017ha marked unit. (Smiley cab)

With a known working-
Sanken Sps040h (eclipse cab)

Both look identical with identical fittings. Only the wiring into the connectors look different in the larger connector blocks between the to cab looms.

Not done this before so thought I'd better check?
