Working on a Series 1 EB atm. Only part of the instrument cluster that works is the tacho and the low water level light. I know it's not the cluster itself as others of the same type (s pack) and standard type do exactly the same thing. Does the bcm control the instruments? Or could it be something else, I've checked the obvious things. Thx.

In the EB1 all the sensors are direct feed and do not go through the ECU or the BCM.

I presume we are talking about the mid series cluster with the six guages?

It is possible the power input is not connecting properley.

There is a pinout chart in the tech docs section, found under the Resources Tab at the top of the page, that will tell you what pin does what.
