accessing horn wire 2007 nissan sentra

Hi All I am hooking up a Viper 4806v my my 2007 Nissan Sentra. Everything is working except the horn wire connection. Everything I have read pointed to pin-3 on a grey 8-pin plug under or near steering column. Unfortunately, i can't find it. Can somebody point out where it is. And how to access it - by that, I mean do I have to a) take out the steering wheel, b) plastic molding around it? I have removed all the moldings and supporting metal frame under the dash on the driver side - that's how I access the mojority of the wires; just having difficulty finding the horn wire. Any help/directions/pictures would be much appreciated. Regards, ttokttok

Remove the plastic shroud around the steering column (right behind the wheel, 2-3 Phillips screws hold it together) there's a grey plug on the bottom

Mark, thanks for the quick reply. I have looked at that plastic shroud around the steering column, and have remove the 3 screws on the under side (of the shroud. But it appeared to be a solid piece around the steering column, and it would not move. The only way it can come out (besides the steering wheel, there are also the turn signal lever and light lever to deal with). Unless I am wrong and the plastic shroud is actually 2 halves, is it? I have looked at it multiple times and it appears to be to be a solid cylinder going around the steering column. Looking forward to hearing from you again, with clarification, if possible.

Remove three screws click out the top then work the lower away. All modern cars are that way.

Howie, thanks for the reply. I will give it another crack tomorrow. Thanks for the help again! Regards, ttok ttok

I was vague, once the screws are undone, pull down on the lower end, use a plastic trim tool or flat screwdriver inside, wash/wipe or lights aperture to prise top away then drop off lower end, the top is "snatched" away.

The only variation, VW, Euro GM use internal screws, accessible once the top is levered off, also some Euro GM, Toyota, Hyundai Kia also use screws facing you, turn steering wheel to see them.

Hi Howie Thank you for your enlightenment and clarificcations. You are absolutely right, they are indeed 2 halves - I was fooled by what appeared to be perfect seam! With your guidance, I was able to take the two halves apart and access the green horn wire, again my sincere thanks for your guidance! Sir, you are a scholar and a gentleman, and I thank you! Have a great day! ttokttok

Did an install many years ago on a CRV, woman complained I'd cracked the cowl around the steering column. Of course she'd never looked before and noticed the seam.
