Thank you Morris,
Maybe because of the shape of the neck braces (and the fact my harness seems a little short here and there) I have talked myself into running it inside the braces.
With the sweep at the top on both sides, it looks like they were put there for the purpose.
I am just going to have to modify the harness to work on the outside, I think it will be much easier to wire in too.
Thanks again,
Lee
