My trailer lights have not been working correctly and I looked under my truck and the harness that connect my 7 pin trailer plug is corroded as well as my plug it self. I just purchased a new one so I can get back on the road and towing but I can not find my tester light and need to get this fixed asap. The new 7 pin plug has different colors on the wiring so it is not a simple match. Here is a picture of the harness. Does anyone have and info on what each wire does?

3 pin connector has:

green with red stripe
black with light blue stripe
brown with lavender stripe

4 pin connector has:
red with white stripe ( tailights)
light blue ( trailer brakes?)
black ( ground ?)
black with orange stripe

Thanks....
