Samurai Tail Light wiring

[HWdesign_imp]

Hi

I am in need of a bit of help.

I purchased the tail light from Samurider. It came with red/black/yellow wires.

The 2013 bike has black-brown, green brown and green yellow.

Tried this and no go.

black/brown wire on the cb to black

green wire on the cb to the red.

tried touching the yellow cb wire to a bolt and bammo. Fuse blown.

Any help would be appreciated.
