I done this the other week. I didnt do it acording to the haynes manual as that said I had to take the injection assymbly off and a load of other stuff which was a bit long.

1. Take off the air filter.
2. There will be about 6 or 8 nuts on the back of the cylinder head around each manifold port. Take off the ones that are holding in the inlet manifold (the injection assymbly)
3. You should now be able to lift the inlet manifold away from the cylinder head and upwards. You may want another person to give you a hand holding it while you renew the sensor.
4. The sensor can be found, if looking at the engine bay infront of you, underneath the inletmanifold on the right hand side.

May I ask what the reason for replacing this sensor is? I had a problem with my temp gauge always going high, then would work and go high again. I replaced the sensor, still didnt fix the problem. It was some dodgey wiring behind the interior clocks, took apart the dash and clocks and the connector was hanging off. Now it works like it should.

Yer pretty much, dont be affraid to use a bit of force tho!
[EDIT] It is also advised to change the manifold gasket when taking any of the above items off. To do this, just undo all the nuts and pull the manifold away so you have enough room to take the gasket off and replace it with a new one, make sure you do all the nuts up tight, run the engine to warm and give the another tighten.

THe temp gauge on the Injection Minis is supplied from the ECU. The sensor in the inlet does not feed the temp gauge!

If you have completely removed the original behind the wheel clocks with something else, then simply connect your temp gauge signal to the wire that was for your original temp gauge

If you want to add another temp gauge, you are going to have to either 't' into the wire feeding the original temp gauge, or drill and tap the cylinder head or thermostat housing to fit an original temp sender

Or what is the full workings of your dash, 3+3 is a little non descriptive!!??

Thats a mechanical gauge, and you are going to have to drill the head and fit it there, the hole in the head is visable under the thermostat housing, it will need drilling through and the threads tapping to the size of the bush on your gauge, fitting it in the top of the thermostat housing is not an option as it will stick up too far and hit the bonnet.

david, in the last pic you posted up, in the bottom right hand corner is the thermostat housing (the metal thing with the big ol hose joined to it!). underneath that, if you follow the head down a bit, you might see the start of a hole (depends on when things were made, i cant tell you whether it would be there or not) - basically its not been drilled yet. thats where you need to drill, so when you look through the hole, you can see the base of the thermostat. you then need to get a tap with the same thread as the sensor, and cut the thread in the hole.
to be honest if youre really unsure/think you'll mess it up, take the head off, take the head and sensor to a good machine shop/engineering firm and ask if they could do it for you. it probably cost less than buying the right size drill bit and tap & tap holder, which can be bloody expensive.
