Well i think so .. first of i powered up the solenoid 12v and the power steering is a lot better now then ever before, much lighter , the solenoid is on the driver side , if you look under the car you will see it, its on the rack itself , this has never really work in my zed , the steering was OK (ish ) but way better now , i'm not 100% what this does or how it works ( yet ) , i believe its the high speed isolator so it can harden the steering up at speed , either way this is way softer now and work great , ( i wounder what it will do up top .lol )
