Mystery wire...any ideas?

[landrovered]

I found a wire that I cannot identify.

It comes from the passenger side of the center console, it is laying behind the passenger seat.

It has a black casing that is rectangular in cross section
It contains four wires that are very small guage
They are red, green, black and yellow
The copper in the wires are filiment and not solid

I hooked a speaker up to it and it is not from the stereo

Any help appreciated.

it's the power cord for the phone option. Can be used to power options by splicing into the wires or using the pins. Here's the schematic:



And in case anyone is color blind, here's the schematic using the plug to describe wire placements.



I think the MY '97 and '98 only had 3 wires, not 4 FWIW.
