Pos or neg horn connection to steering wheel switch?

[BenWA]

I ordered a set of Hella Sharptones (yellow). I will be installing them sometime in the next week. However, I see that I need to know if the horn is connected to the steering wheel switch with positive or negative. How is the 03 Vibe's horn connected?

EDIT: I'm now pretty sure it's positive (the wire that connects to the stock horn is what is best to feed from for the Hella's relay) but I'll still wait for a reply.

Here is the horn wiring in the pdf file that is attached.

Yeah it looks like the wire at the factory horn is positive, not ground. Ground is fed from the mounting bracket.

Thanks.
