Hm, unfortunately, I don't remember, how I did it, if u are talking about ignition switch. If the dashboard prevents u from placing it in place, unscrew theese two bolts that are holding dashboard on right side, that will allow u to pull dashboard back for some cm's, I think, that must be enough. The same thing is needed, when replacing air con fan, at last on LHD B3/B4's

Thanks for the info.ie 2 bolts managed to get ignition lock fitted:rock
Replacement instrument panel arrived ,plugged it in everything working but no autocheck,hmm.The old one had 3 plug ins and had a fuel consumption computor,this one has only 2? Is that another failure? I have abs and battery light on the front.Do i need a special instrument cluster for 90 20v Sport which has slightly different spec.Still got to bleed brakes and check

So, does it have two warning lights instead of auto check as base speedometer? As we can see here and here, third connector - C - have only one purpose - auto check. I only don't get the idea where connects B connector, because it have only 10 pins, it isn't like other three other connectors, but it doesn't care anyway - it's for on board computer and not autocheck. As I said - in your case I would dismantle speedometer and look for broken electrical paths and when found, solder them with some wire, that's the lightest damage possible there

P.S. I still don't get the idea how does MOT can tell before driver that calippers are stuck? When they are stuck, "driver feels power loss of car and wheel is unusually hot even after some miles in city"
