Navara cruise control lights not working?

I have a 2010 navara king cab, as this nav comes with no cruise control i have updated it, the loom is the same across the board on navaras so it is only a matter of adding a clutch switch, second normally open brake switch and steering wheel switches and hey presto you have cruise control. the only problem is that it all works as it should with the exception if the cruise and set indicator lights, these are inoperative, any one have any suggestions?
