I just installed a keyless-entry/Alarm system on my '94 C280, but I can't figure out which wire in the steering column is for the horn. Can anyone give me a push in the right direction?

I dont know if the horn is on the switched side or not, I would find the horn relay and supply the needed A+ or A- to that, or a seperate relay that feeds the horn(s).
just my 2cents

Thanks Peter, I'll give that a try!
