I have a new Hall sensor and a replacement harness-side connector, but I need some help determining which wires to connect the pins to in the new harness connector. In other words, which wires are pins 3, 2 and 1?

Here's the wiring diagram:

Try this, step three. There are no numbers on the connector.

Doc, there are numbers on my replacement sensor's connector, but all I'm really after to figure out the position of the wires on the harness side connector is Red=, Green=, Black=.

Thanks for the link to the 928 thread -- is the EZK mentioned the computer connection?

From the looks of the print, red is 1, green 2 and black is the shield 3. But to make sure use a multimeter and check resistance from the ecu connector to the sensor connector pins. Ecu connector pin 12 is pin 1 red wire on the sensor connector, ecu connector pin 8 green wire should be pin 2 on the sensor and the shield is 3. Hope this helps.....

Well, it's pretty easy

1 > red
2 > green
3 > black

Just as it appears on the print.

The EZK is half of the computer in a 928. It controls spark, and the LH controls the fuel. They talk together via a few lines.

Yes, I have a brand new sensor that's pre-wired with the plug (red, green and black) however, since my harness side connector is missing, I need to replace it. Thus, I need to know what red, green and black plug into on the harness side.

I must be missing something completely...

If all of the wire colors are red, green and black, then the connectors only fit together one way and you can line up red, green and black into the plug on the harness side connector so they correlate with red, green and black on the sensor side connector.

If the connectors are anything like network or computer cables, then the numbers pass through, so pin 1 on the sender side will correlate with pin 1 on the harness side. If either connector has numbers on it, then you know the numbers for the mating connector.

If you have different colored wires on the harness side than red, green and black, then the post above should still apply, e.g. for brown, white and black, where it indicates "connect white to pin 1, brown to pin 2, screen to pin 3".

If that doesn't help, I'm at a loss without pictures of what you're dealing with.

This really does help, and I apologize for missing your post until now!

This was the missing link, thank you.
