Clock loom

[cobra148]

I'm thinking of removing the DID time/temp display and replacing it with a white face analogue clock. Would this be a straight swap, or would I need to change the wiring?
Thanks

I used to have the black faced clock so I would assume the wiring would be the same, you would need 3 wires, a permanant live, an earth and an illumination feed which is a white wire with green tracer.
