This customer purchased the item at our site.
Great product, would have given this a five star if it only came with instructions or indication of what was the output side or vice versa of T-harness. I figure it out that the red wire from brake modulator (one of the yellow wires on T-harness) goes to bike harness side and the blue wire from brake modulator (the other yellow wire on the T-harness)
is the output side which goes to taillights.

Advantages: Easy to install as long you find out wires goes to what.

Disadvantages: None, at this time.
