Alpine 7148L wiring

[Mikewbennett]

Hi, I’ve just acquired a 1983 ish radio cassette as above, struggling to work out the wiring, just 6 wires to a plug plus the ground.
I am thinking red switched +, yellow permanent + ( maybe), blue antenna (?) green and brown + for speakers, black for speaker common ground.

any thought or advice please on testing.
thanks
Mike
