They are so simple - the hardest part is putting in the switch either on the console or steering column housing.

The black box itself plugs into the Suspension ECU which is under the drivers dash within easy reach. You just unplug the suspension ECU plug and plug in the LLAMS ECU into the Suspension ECU then reconnect the suspension ecu loom to the LLAMS ECU - the LLAMS ECU in my car is held in place by velcro dots to the suspension ECU.

The hard bit is finding a spot and installing the switch.

After it is all in you just calibrate it and all is done.
