The air horn kit includes a relay & a connection to the factory horn as a 'trigger'. I wish to cicumvent the extra switch inside the cab by using a hot-when-on connection under the hood on the passenger side.
Better yet a ground-when-on connection ( doubtful that exists).
I tried a gnd to the provided relay which allows all horns to work together, but of course this would put a drain on the battery with the key off.
I would have provided an attachment indicating the wiring diagram, but the forum system doesn't allow for attachments.
