I suspect though that if you have pulled the leads off the DIS you will have no idea what sequence to put them back on in. I guess the TU engine has the usual 1-3-4-2 firing order with #1 being the plug at the cambelt end (left hand as you look at the engine) but of course you need to know which of the "black plastic" pieces relates to number one. You may be lucky and find both the plug leads and the DIS unit are marked with corresponding numbers, but I don't know so.
