Well, it's been a month, and I haven't posted up any progress 
Given the wiring harness has a few weak parts....I've been trying to isolate a few circuits- which isn't easy to do without a diagram.
I went on eBay and bought a 'blown-up' harness diagram for around $20.00
This is AWESOME! - it's for my year, (74) and it is correct as far as I can tell.
eBay Store - Prosperos Wiring Diagrams: BMW Motorcycles, MGB, MGC, Other MG, HD XL Series - Sportsters
Check out his eBay store for the proper diagram for your year- so much easier to read over the FSM's.
Anyways....I'll let you know once I get the dash installation complete, as I've got to work on the 12V output on the dash later today.
More updates in a bit-
