Review: Time saver and worked fine - Worked fine. MUCH faster and easier than building my own. Seems like pretty good quality and there was plenty of wire available to run it where I needed, possibly even too much. I may get in there and clean that up sometime.
Review: Makes the job a snap - Good value for the money. I could have made my own harness, but it wouldn't have been as nice as this and would have cost more to make. Ring connector for the battery +, Ring terminal neg to the chassis ground, female spade lugs for the Hella Horns, male spade lug for the relay +, and wire looms covering all the wires. The male neg spade lug is for the relay. This one through me. All the grounds have continuity to each other, and the ring lug connects to chassis ground, but the one male spade lug neg must be connected to ground or the relay won't work. This one you can also connect to chassis ground.
