EDIT ( I've now found that with a bit of wiggling you can simply release the cowl by undoing the 4 screws and ease the cowl forward and rotate anticlockwise to get it out of the way and then remove the 4 screws holding the instrument pod. This means you don't have to remove the steering wheel or disconnect the mirror control and dimmer
If, however, you decide to take off the steering wheel and column shrouding to make the job easier. Follow below.
To remove the steering wheel, first disconnect the battery. After 15 mins or so, remove the airbag.The air bag is held on with two Torx30 bolts accessed from the rear of the wheel.
Then disconnect the yellow plug, and put the airbag aside.
Loosen and remove the 19mm retaining nut, and then unplug the multi plug. You can then pull the wheel towards you to remove it.(mark the position of wheel on centre spline for refitting)
It is vital that you take measures to ensure the contactor doesn't rotate or it may be damaged.
The column shroud is held with 3 screws underneath. 2 near the stalks and 1 at the bottom under the fusebox cover.
So, the outer cowl of the dials is held in with 4 screws, two shorter ones here
and two others here
You can now ease the cowl forward to remove the connectors from the dimmer and the mirror control.
It was at this point I realised I should have taken the steering wheel off.
The instruments are also held by 4 screws, two here
It is now possible to pull the instrument pod forward to see and release two long grey connectors and a short yellow one.
Don't forget to plug the lightbox back in.
Now you need to replace the instrument pod into the dash, feed the wiring in, positioning the transformer where it won't knock or flap about.
Refit the four screws to hold the pod in place.
Now you need to decide where you are going to position the control switch/dimmer.
You can see my position here.
Refit the cowl.
Now you will need to pick up a live from the sidelight/instruments circuit and an earth.
the middle spare connection between the two I used for the heated seats is a suitable live.
The three connections are, left to right 1/.ignition live 2/. Lights live 3/. Permanent Live.
I managed to remove the dails from my MK1 without removing the steering wheel, not having the gear change buttons may help. Removing the rubber cover from the trip meter reset button makes all the difference, then gentle wriggle it out to the right.
However before it comes out you have to disconnect the speedo drive, this is done by closing the white fitting at the end furthest from the actual speedo. It may be quite difficult the first time but the design has improved over the 1980's MGs which helps.
