I'm new here and wanted to know if someone has the wire diagram for a 2003 hyundai sonata. The factory harness is cut and I have no idea which wire is which, other than BROWN / black is the ground.

I've checked everywhere else with no luck.
I have the following wires.
BROWN / black
black
two yellows
two oranges
red
brown solid
BROWN / white
tan
grey
(odd)grey color
green
light green
blue

Any help would greatly be appreciated. I'm at a loss here.

I'm sorry. I believe the ground is BLACK/ orange and not BLACK/ brown. the colors are hard to make out.
