2002 Civic, 7th Generation Dual Horn Setup with Aftermarket Harness
I used this harness to add a Hella dual horn setup (HELLA 012010911 Black 12V BX Trumpet Horn Kit (Honda)) on a 2002 Civic, 7th Generation. This harness should work at a minimum for 2001-2005 Civics with a single wire horn circuit. The harness was not long enough to reach the passenger side of the car so I added about 4 feet of 20 gauge wire and loom. I mounted the second horn on the passenger side in an existing bolt hole with the lengthened harness zip tied to the bottom of the core support. I used the factory location for the first horn. It was pretty easy to install overall. Functionally, there's no issue with the horns at all. They sound great using the existing OEM wiring circuit. I modified nothing on the original harness. If the horn harness were longer I would give 5 stars.

Look elsewhere
The quality of this converter was very poor. The clips to clamp down onto the horn broke off almost immediately and became loose and would not stay secured. Got another one from AliExpress which was far superior, longer and more durable, even the internal wires were thicker.

Fits Ram 1500 2019-2024 (DT series)
Fits Ram 1500 2019-2024 (DT series). The wiring and connectors were of good quality. This harness has great functionality. I used this harness to add a train horn that is triggered when the horn “button” is pressed.
