Where does the wiring go.......

I am having a bit of a problem with front indicator wiring on a 110.
Taken the light cover off the front to access the wires in the front wing, and I have got no current coming to the connector block. The loom disappears back towards the cab, do I need to take off the plastic wheelarch / splash panel to get at it (there are side repeater flashers so presumably there is a joint there somewhere which may be causing the problem).
Sorry if this sounds a bit dim, but I don't want to pull off and probably break some of the clips etc if its not necessary.
Thanks in advance for any help.

yes, connectors between spat and inner arch. push pin through clips with suitable size drift.

Thanks for that - will have a bit of a poke round under there in the next few days.

You may be able to get to it from the engine bay.
