    Warning horn not getting ground

    Hi, the email notifications don't work for me, so I'm only seeing your message now. Thank you for your offer. I started looking at this because I saw somewhere that the horn is supposed to come on for 1 or 2 seconds when you turn the ignition on, which it doesn't. grounding the wire connecting...

    Warning horn not getting ground

    It doesn't tell me anything I'd want to know. For instance, which pins of the ECU receive the oil pressure and water temperature signals, and which one activates the ground on the horn.

    Warning horn not getting ground

    Sure, but first I need to know where it goes. The signals coming from the oil pressure switch, and from the engine temperature switch, are supposed to go through the ECU which in turn activates the horn. So far I'm not able to figure out which ECU pins are involved.

    Warning horn not getting ground

    yes of course. The issue is that the path from the sensor wire to the dashboard is all hidden in harnesses. I can't figure out how to access a midpoint. There's probably one at the ECU though.

    Warning horn not getting ground

    Can you share more about these connectors? It's impossible to follow the wires through the harnesses.

    Warning horn not getting ground

    Warning horn not getting ground

    I have a 1994 OMC Cobra Ford 5.0 Engine. The warning horn does not work, whether when I turn the ignition on, or when I simulate a failure by grounding the oil pressure switch. It gets +12V through the purple wire, but not -12V through the tan wire. Where should I look next?

    Replacement Trim Hydraulic Pump for OMC Sterndrive
