to bypass that most people will just ground that wire so it will fool the unit to think that the handbrake is always on. some people run a switch in between to control "when" the handbrake is on/off.

yours being a factory OEM unit might be different as Honda might use a more complicated method BUT since it's not a fully integrated unit, there might just be a chance it's similar to an aftermarket unit. i guess if you are not familiar with this, best is to visit an audio shop. ask them to have a look if it's just a wire and get them to solder a switch in.
Any recommendation which audio shop? Can AutoBarn do it?
