Reconnecting low-oil sensor, need help!

[Mali]

Hi all,
I've got a 1994 Mariner 40, 2-stroke, 2-cyl with #0G082938.

The previous owner have disconnected the low oil sensor, probably due to the in-tank-magnet coming loose and alarm stays on. I want to reconnect it to make sure that's the case, but I can't find where to reconnect the two light-blue wires from the sensor!

I've located 4 unconnected cables that might originate from the alarm module, but the colours don't match a schema I found (black and light-blue cables should connect to the two light-blue).

In the first picture, am I on the right spot and if so, what cables should I use? The colours I can find on unconnected cables are purple, pink, gray-blue and white... Please help!

The second picture shows four other unconnected cables, but those seem wrong, right?

Thanks, that's the schema I found. But like I said; "the colours don't match a schema I found (black and light-blue cables should connect to the two light-blue).", so my problem is finding the light-blue and black.

Did you try to trace them down from the TPM (timing and protection module)?

Or the othe way around? From the main harness, follow the tan/blue wire to an adapter then, on this adapter, you should also have the light blue and black wires you were looking for.

The tan wire at pic #2, wich I believe is the connection for the lead from temperture sender, is also disconnected. No sight of the tan/blue. I guess both oil and temp is out... I tried to follow the harness, but got lost under the plate and behind the starter. I guess I need to start removing parts to get a better view and try to find the adapter. Have you got any clue of what the four wires in pic #1 (purple, pink, gray-blue and white) are for?

Thanks for helping out!

Just an update in case anyone else is struggling with something similar;
I removed the plate holding the TPM box and voltage regulator and finally found the adapter where the black, light-blue and tan/blue wires were connected.

It turned out that due to time, sun and Murphy's law, the black had turned into grey-blue and light-blue into white. The tan/blue had a black cover all the way into the adapter, making it really hard to locate without the schema.

So, in short, the wires I found in pic #1 where the correct ones. Connecting "black" <-> light-blue and "light-blue" <-> light-blue shot off the alarm continuesly, so I was probably right assuming the magnet came loose in the oil tank and the previous owner got sick of the beeping...

Thanks for helping out.
