Review on FARBIN Car Horn Special Plug Compatible with Honda Adapter: High-Quality Wiring Harness Pigtail Socket for Effective Car Horn Connection - Set of 2 by Cris Drew

Used this product to connect Hella horns to my 2020 Subaru Outback. The adapter worked well for connecting to the signal cable. The main issue I had was that the wires are very short, honestly they should be around 2-3 inches longer. I was barely able to attach the ground wire as it was so short and ended up having to bend the female part of the plug to make it work. Another thing to consider is that the wires are VERY thin, maybe 18 ga. Alternatively, plug-and -Play , it will probably work for a while. But if you plan on using a relay (which I will eventually do) I would update the ground and not trust this setup.
