I've been through the very long sticky on wiring aftermarket headunit but can't find the answer....
On my harness that goes to ISO A (power connector one) there are a total of 7 wires. I can only find instruction for 5 of them though... What do they all do?

I have blue, yellow & red on 1 row and red, red/green, orange & green/white on other row.

Its a 256 pre facelift that did have cd multi player
