Hi, I’m new to trucks, I have a DAF lf45 library bus that’s a campervan now, but it doesn’t have the control box for the suspension. The ECAS warning is on the dash, the arse end looks lower that the front. Does anyone now if all ECAS control boxes have the same socket plug ? Mine looks like it only has 4 pins inside, the ones on ebay have 6 pins. I’m abit lost at this, I need the box I take it to get the bus level ? Can anyone help me and point me in the right direction please ?
