Looking on the website that was provided for the wiring harnesses, it has two, one for the head lamp and I am guessing the "main" harness. Thing is I do not see the large red wires for the negative side (I am familiar with positive ground).

Do you mean the heavier gauge battery/starter cables? You will find those in Group 12 section of the parts book, and thinking 'positive ground' isn't really that much different to thinking 'negative ground' once you become more familiar with it. You could of course convert it to negative ground if you wanted to.

Again, a lot of this will be fairly new for me on the hands on aspect.

Just take time to study the parts book and workshop manual and wiring diagrams.

Thank you for the complete picture. I never noticed one like that before.

You will find that clubmanracing.com has VERY competitive prices on stock Norton parts. I purchased the bulk of the parts for my Mk3 from them. No issues with fitment, ship time or otherwise. I did a side by Side caparison between those guys and some of the other big hitters for Norton parts (several of whom I am very loyal) and found a savings of over $300 on big parts like the harnesses you need, master cylinders, etc, etc. I would recommend the power arc ignition from Old britts, tho. Talk about set it and forget it! PM me and I can give you a full list of part numbers and prices from the various receipts I have which will give you a clear view of what you're in for as far as time, sweat equity and money. I love these mk3 bikes and have restored 3 now. My latest is probably headed for the auction block soon. Life is taking a bit of a turn for me right now, so my bike addiction may have to make way for my Italian car fetish! Cheers and best of luck. These bikes really are simple once broken down into their individual systems. Even the novice can achieve greatness with a little bit of research and dedication. This site is probably the best start for you. The wealth of knowledge here can far surpass any info given by your manual- which can sometimes seem like theory. Here you will find theory and application in practical terms.

May seem obvious but get a factory maintenance manual and parts book.
There are at least two important nuts that are left hand thread and you will definitely need to know which ones, plus torques.
OldBritts does show parts exploded diagrams including links to parts for ordering which is useful.
I suggest when you get the new wiring harness to install simultaneous with removing old harness so you can see exactly how it hooks up.
Dialectric grease in each fitting a good idea.
In the standard wiring harness there are a lot of unused wires ment for the police version with its lights, radio etc.
I've been told Commando Specialties has a simplified main harness that omits all the uneeded wires which is nice.

Maybe tell us a bit more about your mechanical skills, we noted the disclaimer, but it's best to have an idea where to start. Have you ever done a valve adjustment on a bike? Threaded or modern shims? Changed you own bike tire? Changed the oil and filter? Do brakes on your own cars? Do you WANT to be armpit deep in wrenching (the accomplishment satisfaction thing)? Or rather spend time riding it and let the heavy wrenching be your trusted mechanic's joy?
