T4 diff lock (EDL)

[Seano]

There seems to be another vac line from else where, ABS system perhaps that is connected by a small cover into an electrical line.

If the diff lock is vac operated, I assume then the electrical connection is just a warning and indication light for the dash....

The 'other' line into the diff is probably the sensor hooked into the ECU (which mine has)

The electrical connection at the switch is almost certainly just for the dash mounted warning light but it must hook up to your ECU at some point given you have ABS and the book says that in vehicles with ABS an audible signal will sound if you go over 45km/h with the diff lock engaged.....

The missing airfilter gauge and difflock switch can be easily explained. On some vans the Ambulance upfitter added the extra radios on the lower dash, where the gauge would be. I've also seen some early vans with the switch panel there as well, iirc there were a couple of companies doing the conversions. As for the difflock, chances are it was disconnected early in the vehicles service. Ambulance drivers aren't known for being gentle on equipement, you should see the carnage they caused on the Sprinter 4wds!

Thanks for your reply. Any ides who the ambulance upfitters were. There may be a chance that the dash peices are lying oround in their warehouse. Wishful thinking I know but one must try
