Adding a cabin temperature guage into a Discovery 300TDI

How to install a temperature gauge into you Discovery

Now I have re-fitted my roof lining I wanted to add a temperature gauge into the cabin, for no other reason than to tell how hot it is when I.m out and about.

I purchased from ebay a small battery digital car thermometer, the type which needs to be installed into a panel.  I had a spare place in the roof just behind the interior light, I believe this is normally where an electric sunroof control goes, mine does not have one so I thought that would be the best place to put it.

So I popped out the panel and drew around the gauge to work out where I needed to cut a hole, then with a small drill I roughly cut out the hole.

I then used a sharp knife to cut the section out and tidy the edges until the temperature gauge fitted, they clip in so the cut needs to be quite accurate.

I then popped the temperature sensor behind the panel and just in the cabin where you can 't see it and pushed the panel I had taken out back into my land rover, bingo...

I can see the internal temprature...  Go me!
