moving from concert I to concert II should it be a straight swap?

The reason I ask:-

had taken out the original concert tape player and fitted an aftermarket nakamichi unit, but it only lit amber or green.... I wanted red.

got the chance of a concert II cd player from a TT (02) on the underside it says C5/TT so I was sure it would work in my 01 A6 (C5)

fired it in and sure it works but it doesn't illuminate the buttons, not very good at night.

I decided to dig out my old concert unit and it looks like there are a few pin out changes (oops should have looked first)

the illumination pin on my C I doesn't exist on the C II.

Anyone got a pin out diagram for a 2002 TT? or would know what has changed
