Fender mounted blinkers
i should say that these little gizmos have got to be the greatest things when working with wiring that you have had to cut. To install, you strip the ends...put them together. slide the base over them until the bare wire sticks out then screw on the cap so they are held tightly together.
They are called Posi twist.

I had two problems. 1) I had one extra wire...not sure it came from and 2) i had connected the wire to a wrong group. My eyes and discolored wires were the culprits. It was weird, I was getting power 2 two wires at the same time vs one wire for the parking lights and a second for the blinkers.
The light allowed me to troubleshoot quite quickly.
