It's a Premier Hazard 7166 from the UK. I believe it takes the high side. Did you go right inside the column, or is there a nice spot in a wire bundle down below?

I finally got around to finding the wire I need. It is indeed the blue with white wire. I confirmed that by grounding this wire the horn blows. Now to use the wire to do horn ring on my siren what do I need to do? I tried tapping the existing blue wire and taking that to my horn ring input on my siren, but that doesn't work. Do I need to cut this wire so the factory horn doesn't work at all? And tie the horn "switch side" from the truck to the siren horn input?
It's the first time I've used this feature, so sorry
I appreciate any help!

And as a note...on the Fords...since it is a low current wire...and you are only using the wire wire from the siren, you might have to use a relay and/or a toggle switch to seperate the signal. The trucks system might not have enough "low" current to drive a siren & the horn.....just a thought.
