Ok Richard thanks for your support, will test them in the next couple days and update this thread ...

[Richard L]

OK. I look forward to the readings.

Can you take a hi-res, close up picture of the plugs of both gauge cable. Long and short. Make sure they are in focus.

Hi Richard, results are in, let me know what you think

Original cable end

Extended, other end is a mirror just like the original, both behave the same ..

One thing stood out on the tests, the red wire of the molex is not correct, Check this wire. Should be A8 of the DME.

It is connected to A8, in fact it is twisted with the other red wire from the ECU harness and tapped into A8 at the same exact point

I will check and adjust that wire, which test point to check after and what should the reading be?

I went back to the car rechecked the red wire from the molex connector and it is definitly in contact with the A8 pin wire ... I even untwisted it from the other red wire from the ecu harness and gave each wire its dedicated contact space on A8's wires ......

Still, the water level light remains, but I noticed this:


When the A connector of the car's ecu is disconnected the water level light goes away, but the gauge background and S led is still working, as soon as I plug in the A connector /harness the light comes back on again ...
