2003 Boxster amplifier male plug

[PLP]

A tricky question...

I am installing a AA/CP 2-DIN unit. I need to bypass the OEM amplifier.
Part number 996 645 331 01
I do not want to splice wires, so I thought I would get a male plug (like the one on the amplifier) and simply create a harness. If it was ever needed, I can just disconnect it and revert to previous state.

Any clue what is the plug type?
Like the radio has ISO plugs, maybe the amplifier has a some kind of standard plug as well.

Thanks for help.

Oh, and l looked on eBay and I may just get some used amplifier and just re-use the plug from it.
Yet, maybe there is a cheaper solution, like the plug itself.
Thanks in advance.

P.S.
I looked up a similar question on Renntech.
It seems it is a dead end street.... but maybe something changed over the years.
