does the clock in the mk1 turbo light up so it can be seen in the dark?
There are two types of clock fitted to the mk1 Uno Turbo (and SX), all fitted in the rear view mirror/ map reading light unit.
The earlier clock uses red LED's (three buttons on the clock), and also incorporates a chronograph (or stopwatch in laymans terms
) This is always lit up, though the intensity of the LED's changes depending on whether the lights are switched on or not. With the lights off, the clock will be in bright mode, and with the lights on it will go into dim mode. The idea being that at night the display doesn't need to be so bright, whereas in daylight it does so it can be seen better.
However, there is a fault in the design that occurs after a few years. The fault causes the clock to overheat and reset itself when in bright mode. One of the components inside the clock gets very hot and breaks down - I had my first one repaired and it worked fine for a few months then started resetting itself again. Both my clock units did this. I got round the problem by re-wiring the clock so that it is always on in dim mode. No more resetting, though in bright sunlight it can be a little difficult to read the display.
The LED clocks are quite rare now, and were superceeded by the later LCD clock (no stopwatch, only two buttons). The ones I've seen, and I have one in my spares, use black LED's and are backlit in green. I think they also have a dim and bright mode depending on whether the lights are on or not. They are backlit by a small bulb that is soldered into the circuit board, and after a few years these bulbs burn out. You need to take the clock apart, unsolder the old bulb (I think it has three joints), then find an electronics store (Maplins?) and buy a replacement. Solder it back in and you should have a backlit clock once again.

how do you wire in the boost guage on the digital dash?
From what I gather, the analogue dash takes a boost pressure vacuum pipe from the engine bay straight to the back of the instrument cluster, whereas the digital dash has no provision for a vacuum pipe. I 'think' the digital dash uses an electronic sender instead of a pipe. Someone else was looking for this a while back too
, and I know Louie was going to have a look on his mk1 sleeper turbo to find out as from what I remember his also has a digital dash.
I recall having a look in the Haynes manual wiring diagrams but couldn't find anything about a sender for the turbo boost gauge. By the sounds of it you'll need to find someone who has a working digital dash and see how it gets the boost gauge connected. Maybe Louie did find out and can let you know?
By the way, attached is a picture of the earlier mk1 roof clock in all its red LED glory
