So today I decided to try the bumper signal mod. While doing this I have ran into some issues.

1st round: Never cut the blk off the B/S and tapped it to the green/yellow. Result: Lights never flashed on.

2nd round: (correct version I thought) Cut the blk on B/S and tapped the end running to the B/S to the green /yellow.
Result: Blinkers work but not the Bumper signal.

Where am I going wrong?

Also I have led bulbs in.
