'84 240 speedo cable

[Greenthumb]

I decided to replace my instrument cluster from a "pull" yard hoping
to get a speedo that works.

So far, so bad.

I have the cluster out, examining it.

I see not one but two openings that look like they want a cable.

One is dead center and I guess a cable under the dash hooks to it to
drive the speedo's gears.

But there is another, roughly behind the "80" as in 80 mph. It is
white, threaded, and sure looks like a cable threads to it.

But I don't see another cable under the dash.

Am I missing a cable?

Or is the white threaded opening just there, for something else?

I found a short cable loose, about 9 inches long; looks like it ought
to fit something. Right now it is on my table.

The white threaded opening protrudes about half an inch from the back
of the speedo.

I've checked two aftermarket Volvo books and neither provides a clue.

Can there be two speedo cables?

That other cable drives a little box that turns on the Lambda light after a
certain number of miles to remind you to check the emissions system. It
loads the odometer and can lead to cracking of the drive gears so most
people who know about that remove it as it really serves no useful purpose.
Yours was probably yanked out by a previous owner, I removed mine a few
years ago and threw it in the trash, never missed it.

In countries (like Canada) that didn't have that legislative
requirement, we sill got speedos that had the provision to drive that
counter - but nothing was connected to it.

James is right. That was a short cable that went to a small box just left of
the steering colum that accutated the Lamda light.
