Starter Button, Turn Signals, and Headlight stopped working 1977 KZ1000 A

Many thanks to all prior to writing this.  I checked the forum for my particular issue...if it has already been covered, please point me in that direction.

OK, this is my first KZ1000A, and it is one of the first/early ones.  It has a 1080 overbore kit, Mikuni VM29 carbs and a 4 into 1 exhaust, with necessities like K&N pod air cleaners ect...

I rebuilt the carbs, and got it to run, no problem, but had to play with the electrical connections, cleaning all of the connectors with DeOxit-D5 and scruff pads where I could.
When I first received the bike the start button did not work, I trouble shot the starter, solenoid, and push button, to finally get it to start...just by what I thought my efforts of cleaning the contacts.

I have had the wiring loom somewhat laying free, while I got all of the electrical stuff working and getting the bike to run.  Yet when I organize the loom either with panduit or cable ties, the start button will stop working along with the headlight, and now turn signal dash indicators....I take everything apart, re-check the connectors, play with the wiring...checking the solenoid, starter ect...all the electrics magically come back to life, I try again to organize the wiring, just to get the gas tank back on, and then the start button and other items stop working....this will be my third time.

I understand it is a wiring loom issue, since it is the original loom.  I have checked the ground, and used many of the wiring diagrams to see what I could be missing...but this is frustrating.

Any ideas?  Typically grounding problems are tough to diagnose, likewise a broken wire that may/may not be covered are tough to check.  But the common issue is that the headlight, starter button, and turn signal dash lights stop working.  Any common items that I should be looking for?

Thank you again, I appreciate any/all feedback.

Welcome from the UK, if you look in my signature there is a link to an electrical fault finding guide which I wrote, you may find useful
PS: if the link doesn't work look the filebase - "General" - "General electrical" page 2
