I have a keyless entry system set up so that the horn triggers with every lock/unlock. I have two additional negative auxiliary outputs on this system that are unused.
I would like one aux to disable the horn chirp. This should be a constant disable and not temporary. The second aux would enable the horn chirp (constant enable). The horn has a negative trigger. I thought about using the latch on/off diagram, but I would like to use two separate buttons.
Thanks for the help.

Use a latching relay. This relay will change position and remain like this until next trigger.
