Dr. Hess, I did exactly as you said. Confirmed with the wiring diagrams I have even down to the colour of the wires. Still not working proper. I do however now suspect there is a short and or two wires touching because when I engage the right or left signal switches independently, power goes to both. That I know is not correct. The only thing the owner ever did was remove the front and rear signal lights. Her better half at the time snipped the two right side wires and left side wires up on top of the headlight pot and under the eyebrow, and the the one right and left side wire from the rear signals at the back. I was probing the wires with the switches but never check both sides when I engaged the signals hence I missed that from the start. In other words, if I use a test light on the right side power wire (brown tag) I get power to it BUT, there is also power going to the left side signal power wire (violet) and vs vrs. My limited understand of switches tells me if you press one switch both right and left light should not come on. The harness appears to be in good shape. Nothing else is cut and or corroded what I can tell. This should have been an easy fix based upon the diagram . What and or where do I look for this?

I have disconnected all the lights. I wanted to make sure I had each one wired proper. When I turn the key on and press either the right or left signal handle bar switch, power goes to both sides (the hot wire to the lights) Same if I press the left handle bar signal switch both signal wires light up (right and left).

Dr. Hess, I have done that. Front running lights are on even when not selected. when I run a signal the all blink weakly. The only way I get anything even remotely is to gound out the back light with the running light wire then the right hand signal front and back work however the left sides stay lit and week. Something is crossed somewhere but I only have the four up front and two at the back to work with everything else is wrapped up in the harness. Like I said they cut the wires to remove the originals and nothing more. The signal indicator light does NOT come on at all on the dash no matter how I hook them up. My concern and observation is that when I engage either the right or left signal switch power goes to all the lights.

Hess, I thought about that but what is the issue with a hot signal going to both sides when I push either the right or left handlebar switch? Logic would dictate that if you press the right handlebar switch, power should only go to the right side wiring, NOT ALSO to the left and vs vrs.
I really appreciate you help, effort and knowledge.

The schematic you posted shows the turn signal indicator light bridging the two sides. With conventional bulbs, this would not be a problem, as the small bulb would limit current to the other side and the other side's bulbs would not illuminate. However with LED's, things can behave different.
Also note as I said, the back bulbs do not have running lights. If you hooked up the 3rd wire (running light), I don't know what you will get or what you hooked it to. Disconnect everything, add one conventional bulb to a side on the front, get it working, add the other side, get it working, swap out to LED's.

Dr. Hess, you are a god my friend. There is a doctrine in philosophy called Ocums Razer. In simple terms, all things being equal take the easiest route. I put standard 1157 bulbs in and all works. She will have to settle for none LED bulbs. I even bought the flasher when really had I listened to my own convictions, the problem would have been solved. Thanks brother
