[Healeys] Wiring loom query

[Simon Lachlan]

I have a MkII BT7 3000.....
The grille is out of the car and the front end is generally "get-at-able".
The wiring loom's progress around this area of the car has always been a bit
of a mystery to me and, it seems, to previous owners, mechanics, paint
sprayers etc....plastic cable ties everywhere...all worked but was a bit of
a mess.
So, where is it all actually meant to go? To what is the loom clipped and
with what?
And, can one clip(?) it all in before re-installing the grille then the
radiator? What's the order of play here?
Thanks,
Simon.
