Tapping into OEM horn for alarm

[Tamago]

why not tap it at the steering column as i've already suggested?

Tap the black wire on the white connector in the picture (yours will probably only have the black wire {no blue and brown}), and like Tamango said, it needs to be grounded to make the horn blow.

Perhaps I wasn't clear in my original question. The write-up I found said there is only a black wire coming out of pin 8 of the D3 harness. In my sedan there are 3 wires coming out of the D3 harness--1 black, 1 light brown, and 1 pink and if I remember correctly the black wire was coming out of a different pin (I think pin#5 of an 8 pin harness). Also, I couldn't test the horn because the airbag and horn switch are missing thanks to the thieves.

I just want to confirm that this is indeed the right wire so I can call the installation finished. Pretty irritated with the mess of my car these thieves made...

No worries--I wasn't clear in my initial post. Thanks anyway.

That really stinks!


The horn should be pin 8 of D3 on the Sedan as well as the LB.

Awesome! Thanks for looking that up. I must have forgotten how to count since I thought it was an 8 pin harness but it was a black wire and one over from the end so that must be it. I'll give it a shot later in the week when I get the car back from the dealership. I actually tapped that wire when I had everything apart so it should be a quick plug and play after testing.
