I have installed an after-market keyless entry system on my 2002 Camry LE. I have not yet hooked up the horn for the confirmation "chirps" when locking/unlocking the doors. I have not been able to locate the wire that goes from the horn button on the steering wheel to the horn relay under the hood. I'd rather not run a new wire thru the firewall, all the way out to the relay - much easier to tap into the line under the dash. But I can't find it. I own the service manuals too - they are useless when it comes to wiring diagrams - there are none!
So, can anyone tell me the colors of wire, and the best place to find it?
Thanks
