Ive just had an auto spark try and find out why i have no display? Can someone tell me what each coloured wire into the panel is or does ?
Someone said it has nothing to do with the main engine wires execpt for a power from the split charge relay? Where is the rwlay supposed to be located as because of engine upgrade everything has moved . Its doung my gead in now ive been without van for 18 months now and need to get it sorted
Sorry for all the questions but the mire i can tell spark the better .
Cheers people

You might find this useful - http://www.westfaliat4.info/WestfaliaT4CentralElectronicUnit.pdf

It’s in German but Google translate can help make sense of it. There’s a page towards the end that has a breakdown of what colour each wire is.

You wouldn’t know anyone with a panel you could swap out temporarily to check it’s not just dead? They sometimes just give up. Not what you want to know but it would eliminate the unit which isn’t easy to diagnose without specific electronic know how.

From reading around Pin 10 (red/green) and Pin 26 (red) are both permanent lives. Pin 10 is fused behind the drivers seat by the fuse one. I’m guessing if there’s no power to the camper fuseboard for whatever reason then the control panel won’t work. All other pins are for the various sensors and timer controls.

Tidy. Looks great.

No problem helping out. Just hope it’s accurate enough info to be useful.

Your display should be on permanently. I think it’s powered by the leisure battery, which in turn is charged by the hook up or alternator. The split charge relay lives under the fridge I believe, near the charging unit. It’s probably unlikely to of been messed with during an engine swap.
