Hi i’m looking to locate the 3 terminals on the EAS suspension ecu (RR 3.6 2007) that serve the rear right height sensor to check continuity or replace, any guidance much appreciated TIA

The rear harness is in the black connector that is at an end. The other end is grey (front harness).
5V pin 8 (yellow with black stripe),
signal pin 9 (yellow with slate stripe),
ground pin 10 (yellow with brown stripe).
Looking at the face of the connector, the top row (clip on top), starting from the left are pins 10, 9, 8.

Brilliant many thanks GraemeS

On some models the connector is white but mostly black and always the end connector. I make kits that use a short extension harness that fits between the front and rear harness connectors and the ecu that fits L322 MY07-12, D3, D4 and L320 RRS which all use the same suspension ecu. The L405, L494, L462 and L663 all use another ecu that uses a different set of connectors for which I use a different extension harness.

I snipped off those 3 at the ecu and the sensor and ran a 3 wires between them and it worked! cheers...will be planning permanent fix next
