Get the cruise control stick from China.
Install premio spiral cable.
Connect another wire from cruise stick to ECU.
Program ECU.
You can turn it on at 40km/h speed till 140km/h
Two ways to cancel the cruise one from brake paddle other from cruise itself.
On long routes like on motorway it also gives good millege as the speed is constant. I always put it on when driving through motorways at 120 some times 130km/h.
