Works great! Easy to understand instructions, even for an electrical idiot (like myself).

Quite possibly one of the single best products one can get from J&P. This has everything you need for wiring a bike whether you're building one, customizing, or replacing a poorly designed OEM wire set.

Used this to wire my first custom built bike. Made wiring simple. Don't know how it could be made any easier. Well worth the money spent.
