I'm trying to replace my Civic 1999 horn with some Acura TL High/Low horns

i took apart my front and i got to the horn, but i noticed that the Civic horn has only 1 prong, while the acura has 2

for the civic i figured out that the prong is the positive, where the power goes, and the horn grounds itself to the chassis (from the bracket).

I assumed for the acura horn, it's 2 prongs; one for positive, one for negative.

i ground one prong to the chassis, and one connected to the power.

no luck.

i checked the fuse still works.

Both the civic and the acura uses 12 V / 3 amp.

Anyone got any ideaS?

i was using this as a guide.

It may need two power wires (one for the high tone and one for the low tone) while the ground may be the same as the original (chassis.) Just an idea.

 

tried that, didn't work
