bought a factory radio with pigtail. Can someone confirm I am thinking correctly on the hook up.

here is a picture of the back.

Top plug
GRD I assume these three (4 one not marked) are the

GRD GRD speakers

LF RR These are the power sides to the speakers
RF LR

second plug
LMP Lamp
12V No wire on pigtail but I think it is my battery power
GRD Body Ground

I am assuming the extra red wire running from the back is for power antenna
