oil warning light and battery charge light not coming on

my oil warning light never comes on seen it flash a few times. and my charge light did come on but has quit.

the charge light is blue/white?
ive seen a wire hanging loose, where in the engine bay does it plug into? seems to have a spade connection

the oil light what colour should it be and where does it connect to?


the car was orginally a 1.0L and now fitted with a 1.6 8v with a carb


thanks in advance
