Wiring-In Analogue Clock

[dr.david.lewis662]

My recently-acquired S Type is perfect in every way, apart from the absence of a proper old-fashioned, analogue dashboard time clock. To remedy this I’ve acquired a clock from another model of Jag (see below). I fancy getting a nice walnut surround made for it and then mounting it atop the facia, like a mantel clock in a gentleman's club. However, I need to double-check that it’ll be possible to wire it into the car. As you can see, the clock has 6 pins on the back, and I gather that only 4 of them are active. Can anybody advise?
