You have a voltmeter, right? You're gonna need one.

That makes sense - test them both. I would expect that one's a
conditional power (comes on with the key or maybe the lights), and the
other is dead all the time - it's power to something else. If the other
lead is providing power, touching the two together should make "it" come
on. Label it at this point.
If it gets power with the key, it goes to the red lead on the stereo.
If it gets power with the lights, it goes to the orange and white lead.
There's a light wire to the cigarette lighter if that's missing from
your previous install.

That should be power all the time - this is the one that actually powers
the stereo, and keeps the clock going when the stereo is off. That
should usually be connected to the yellow lead.

Blue is usually for the antenna, but if you're taking it out, you might
as well take it out while you can see what you're doing :o)

Test it - that might be conditional power from the switch. If it is, to
the red lead. If it tests as continuous to ground, then it's ground.
I've got to the point where I test everything - even the stuff I've done :o)

The Bentley won't know about the wiring the previous owner did :o)
