Two different OEM radio types?

[justinae]

I farmed an OEM stereo that looked exactly like mine and realized after it used a different wiring harness. I do have the harness from the supply Ranger. I plan to get a Metra adapter but it has 13 wires to match my factory harness and the farmed factory harness has 15 wires.

When you compare the two:

• 8 wires are speaker and all match
• 5 wires I'm guessing are power, ground, illumination, etc and all match
• But there's two extra: (1) red w black stripe and (2) black w green stripe

What are the two extra wires and what do I do with them?

It might be useful to know the year of the sourced radio
