This product is very well built. However it will not work with my 2011 Heritage. I only found this out after buying it and then buying a load equalizer directly from the manufacturer. I was told it has something to do with the CAN system... Bummer.
Modulator works great. Rear turn signals now act as running lights. I really like how all the rear lights blink when I brake because I feel it makes me more visible from back. I did have to buy the 6-8 pin connector also. They only thing that concerns me about this unit it that it seems to get fairly hot when in use. But I suppose that's what some electronics do. All in all I'm very satisfied with the product!
