Is there anything new on this? I'm still not receiving email notifications

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...

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.

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.

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. If I manage to find it, I might be able to tell if the lack of continuity is before, after, or in the...

Thank you, but it doesn't look relevant.

Everything is inside harnesses that I'm reluctant to open up. I can't find a schematic detailed enough to help. Do you have one?

Well i grounded them both, the sensor still attached to the wire. But even just grounding the wire does not activate the ground at the helm. Any advice?

Hi, I do not get notified when someone answers my posts. I checked my settings, all notifications are ON. It seems like the /contact form does not exist either. How can I get ahold of an admin?

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

That's exactly what I did in the first place. But ground does not arrive at the horn.

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?

Thank you everyone. I ended up purchasing a used pump on eBay. It works great.

Hi, I have a 1994 OMC Cobra Stern Drive model number 50FACPMDA. The tilt/trim hydraulic pump model number 985846 is likely faulty. Since it's no longer made, what can it be replaced with? Thank you Jeanric
