Plug and play... almost!
These worked great with the Hella Sharptone horns on my Toyota. Many comments here complain that the negative battery wire is a bit short but you only need to ground it to any bare metal on the chassis. Shipping only took a couple days too!

Expensive but seems quality
Took a long time to arrive but I believe it had to come from the USA. Not installed yet but have tested and works fine. A simple kit but one which does what I need. Will be a simple installation. My classic Roverโs horns are weak due to no relays and relying on current passing through the 45 year old horn switch. This kit should solve that, providing for power directly to the horns via the relay.

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.

Nice and convenient
Great item, some of the connectors are cheap and can slide off the wire but the whole thing is still great and functions!

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.
