Thanks Steve.

I guess you are Steve Bisel, based on your first name and your choice of first post?

I don’t suppose there is any way to keep the soft suspension setting with the exhaust valves open AND the sport engine setting?

There are two solinoid valves one at the front and one on the rear subframe beam

it’s the rear one you need to wire too not the front one as pictured. It works initially but then stops responding.

you need to run the wires down the NS of the car and cable tie them to the brake pipes then route securely up over to the rear solinoid, not the front one.

An auto you can see and access it easily but on an MC shift you need to remove the OSR exhaust box.

I am going to fit my controller in the boot and wire to the rear solenoid that way.

Makes sense if you can find a way through the boot floor. There is a grommet where the battery vent is that could work

oh, and make sure you piggyback a fuse that comes on with ignition and is not switchable like the Aircon…I went there and gave me plenty of head scratching.

That's the plan or put another grommet in. Piggybacks ready. Does the solenoid plug carry a pos and neg? I plan to direct the power feed from front (ecu) to relay box and back.

Earths to the chassis from memory

if there is a second earth wire that runs back you can simply do as above to simplify it

Yes plan to switch the negative so there is no issues with signals from ecu etc.

I have just added a Levante Trofeo to the collection. Has anyone carried this out on one? I am assuming install pretty identical to the one I carried out on my GT? Just need to locate the relevant pipe.
