[Healeys] Lighting query

[simon.lachlan at homecall.co.uk (Simon Lachlan)]

I have a MkII BT7.....

I want to add an extra light at the rear. In fact, I bought one off eBay for
about tuppence. We'll see how well it works....

Am I right in thinking that power to this light should come from terminal 5
on that Lucas box of contacts, the "brake switch overriding relay". I touch
wood every time I think of that thing!
