Which one of these is the Factory Radio/Stereo Ground Wire?

[Nickshu]

Trying to sort out all the junk under my dash. PO's had various stereos and alarms which I have removed most of.

There are two ground wires to the area of the radio/stereo. I want to know which one is not original so I can remove it.

Check out the picture below...which one is the factory radio ground??



Thanks!

But either will work as a ground (for pretty much anything).

Good luck,

Thanks Gerry! Comparing your photo above to my MY82 current flow diagram shows that the radio grounds to MPIII, so the wire coming from the headlight area is the original ground.
