looking towards the end of the plug, blue grey black brown...... i think or grey black brown if there's no neutral. or could be backwards, haven't had to wire one up for a long time!!!
that links for american wiring, we don't use high leg deltas over here
whats on the other end of the cable? what type of plug is it?
If ias a balanced load (motor ect) in the uk the brown is L1 black is l2 and blue,L3,if its a motor and it goes around the long way just reverse l1 and l2.However strictly speaking blue is reserved for neutral so double check as it could be a 2 phase and neutral supply

think his problem is the pins fell out, with the l1, l2, l3 etc on them and needs to know which order they go back in?
As long as you are not using three phase motors or fans the order in which you connect is not important
if you has three Phase equipment wire up in any order if fans or motors run in reverse just swop any two phase's
hope this helps

thanks for the replies
scraglors about right all the pins just fell out on me
the other ends connecting to a 3 phase steam cleaner, the plug is a ceramic push in, then screw the collar up UK type thing! looks like something you would connect an electric chair up to, scary shit dint fancy getting this wrong ,,so iv left it till tomorrow , and forgot about my posting should the plug be marked with L1 L2 L3 ?
should be yeah, l1 brown phase (or red if older colours) l2 black (yellow) l3 grey (blue) N blue (black)
