Flstf Turn signal wiring

Installing turn signals on my bike. The previous owner chopped the harnesses. Anyone know what the purple, blue & black powers? I'm assumeing that black is ground.

Thanks..

Purple is turn signal blue is running light.

Hey BEAST , I had a bit of trouble trying to to follow the wiring diagrams in my flstf manual [ to damb small ] so I took the manual down to a printing shop and had them blow it up to the largest size they could and mounted it on my garage wall saved me a lot of time and frustration ! damb ,getting old is a bitch!!
if you make your connection so they're hiddin in your fork tins you might want to use male/female connector in case you deside you want to change locations of your trn signals. [just a thought !] good luck.

Great idea with the schematics. Going down today and have it blown up.
