Good day

There are 7 different units or amps found under the seat and it depends on the unit number the pin outs are different
the plug on the left of the unit looking from the rear of the seat is your outputs to your speakers.
The plug is numbered 504 on the standard wireing diagram and they work in pairs for example

looking at the plug starting from the left top on my amp the pin numbers read as below

1 2 3 4 5 6 7 8

9 10 11 12 13 14 15 16

1/9 front left
2/10 not used
3/11 left rear
4/12 right rear
5/13 front right

the rest are not used

so each unit is different on the premium audio with sub 2 and 10 are connected on the
basic radio the complete plug is different so you need to take the number of the unit so a person can help

hope this helps
