2008 chevy tahoe horn ring

[Jay G.]

Doing one next week. Need the horn ring wire. Any ideas where/what color to use? One site I found only said at the horn switch itself. i really dont want to take apart the steering wheel! HELP!
thanks!

For those who need it:
Muiltipin connector with 2 rows on top behind BCM coming from the steering wheel. It unplugs then u can work on it easily.
There are 2 tan wires, one on the end and one in the middle. You want the tan wire in the middle, not the end.

Thanks from another 2008 Tahoe guy. So, what do you get out of that tan wire when you hit the horn ring these days...ground or 12vdc? I'm going to run mine to a Whelen HHS2100 and wanted to know if I can wire directly or have to use a relay to change ground to power. Thanks again.

I would like to revise the question, does anyone know what the current draw is along with the polarity?

Is there somewhere in the Engine Compartment (outside of the Horn itself) lat has a low current version. The SS2000SM I am installing doesn't like high current. Would just assume not have to use a relay if possible.

Thanks Tons!!

Talked to the Whelen Install Shop...if you stay upstream from the horn relay (i.e. dash or prior to the fuse panel under the hood), the horn is activated by ground and is low current (milliamps). Hope this helps. I'm wiring mine this week and will find out for sure.

I find bulldogsecurity.com a good place to find out vehicle wiring information....http://64.85.6.121/diagrams/printpage.a ... &MakeID=54

THe location Jay is mentioning is in fact a good place to tap in as its simply a wire connection from the steering column harness contacts in the wheel to the BCM. You're not activating relays or anything else. Just finished two tahoes at this tap point with no issues. HOWEVER, make sure you properly seat the connector and snap the retainers back in otherwise it won't make proper contact and cause all sorts of funky behavior, including not starting.
