For older Avant models, where the socket of the attachment control switch pack is not in the multi connector system, it’s possible to mount afterwards a connection cable which is mounted on the multi connector system of the machine. A wire coming from the attachment control switch pack is mounted on the connection cable, so that both the hydraulic hoses and the electric wire of the attachment are connected at the same time with the multi connector system. It's also possible to mount a corresponding connection cable on the multi connector of the attachment.
