HOWTO: Installation of an aftermarket replacement horn on a Nissan Cube.

The horn on the Nissan Cube seems very under powered. Here is a step-by-step HOW-TO detailing how to install an upgraded horn. My choice is an "El Grande" dual electric horn from Fiamm.

Hi there, i installed the same horn in my cube and everything worked fine for about 2 weeks, when suddenly it stopped working--i checked the horn fuse and it's good i'm in the process of getting a new relay (existing stock relay) but would you know what else could be wrong i got a feeling it may not be the relay...thanks for any help!

@eCigslounge If the fuse is good (both the inline fuse (if installed) and the original fuse) I'd try connecting the horn directly to the battery first.

The El Grande horn *should* be ok on the stock fuse and relay, but it's better to isolate it with it's own fuse and relay to be safe.

Excellent video. Just wonder where which original horn wire goes to which terminal on the relay. On the Cube one wire from the horn is + the other -. I fear if they are installed on the wrong side of the relay terminal they will create a short. Could the video show which wire goes on which relay terminal? Only clarification i feel needed. Thanks for a great video

@Ernesto1296 Some relays have different pinouts.... The wire that goes to the original horn goes to one side of the relay coil, the other to ground. There is no polarity issues.

Any errors in wiring will either mean thet horn doesn't work, honks unless the horn button is pushed, or honks regardless.

Whats the size of fuse your using didnt mentioned im uour video

[grnbrgb]

@williammerseburgh - Just a standard 12V, 20A automotive fuse.

@grnbrgb That was what I was afraid of. Polarity issues. I checked a few schematics of a 5 pin relay and hooked up as follows:

Positive horn wire to pole #86. Negative wire to pole #85. Other wires were hooked up per your instructions. Works perfectly. Thanks for a great video.
