Hi Mr. Catfish and welcome to Ninjette!
Stop replacing perfectly good parts with brand-new perfectly good parts because nothing will change. You need to test and measure parts to determine if they are indeed bad before replacing. Unless you bought that harness new from Kawasaki dealer, it too is as suspect as harness on your bike and should be thoroughly tested before using. Now you've got two harnesses that needs to be measured and tested instead of one.
One thing you need is new battery. Heathy battery properly charged is very first step. Even if all your wiring is operational, bad or poorly charged battery will prevent bike from running. Anything less than 12.6v is drained and dead. You need to get proper 1amp motorcycle smart-charger and put it on battery for 24hrs. Report back with battery voltage at that time. Once you have good battery with proper charge, then troubleshooting effort may be worthwhile.
