Did u have to bypass any of that when you installed the electronic. Oil pump.

No, when I turn on the key I get one continuous sound, no beeps.

The Electronic oil pump just replaces the mechanical one. None of the installation bypassed those systems.

The horn sounded before I put in the electronic injection, just went away after the engine speed increased so I lived with it. but now it's constant no matter the speed. This (the constant sounding) all started after it came out of it's winter slumber this year.
