Hello,
Please see wiring diagram below.
Please note that the pin out differs from coupe to sedan.
Grey wire is a 5V supply from the control module, that's most likely why you find that the test light was only illuminated dim. best use a digital voltmeter.

Red/black wire is sensor ground.
Use this wire as a ground to test if the 5V supply is good after testing the supply to a good chassis ground.
Test the other three wires back to the control module, ensure that they have continuity and a resistance reading of less than 1 ohm pin to pin.
