Hi here are the connections taken from the back of my nikkai a86fn
Looking at the bottom left hand corner at the back of the radio
top row from left
1st pin red = RCA Line out
2nd pin white L = RCA Line out
3rd pin not sure what this is but seem to be linked with the first two pins
4th pin yellow = memory B+ 3amp fuse
5th pin un-asigned
6th pin un-asigned
7th pin green = + to 4ohm left speaker
8th pin green/black = - to 4ohm left speaker
bottom row from the left
1st pin red = 0.5amp fuse (power B+)
2nd pin blue = 0.5amp fuse Auto Antenna B+
3rd pin un-asigned
4th pin black = ground
5th pin un-asigned
6th pin un-asigned
7th pin grey = + to 4ohm right speaker

Please note the information above is supplied in good faith and cannot be guaranteed as being correct. Full responsibility for in-correct connections and any subsequent damage lies with the person who makes the connections.
I hope the above is of some use having said this I would advice that a qualified radio technician is consulted
