My 1994 E320 wagon has a weird electrical ghost.
When I press the break pedal I loose fuel, oil presser, and temp gauge and the large relay that controls the signal lights start to make a buzzing sound. Also I don't get any tail lights. The marker, signal, and reverse lights work.

Things I have tried/checked

1. I replaced that large relay
2. I replaced the little switch down on the break pedal linkage.
3. I checked all the grounds behind gauge cluster. " Very Clean No Corrosion "
4. I checked all the wires in fuse box and wires in rear connecting to tail lights. " Very Clean No Corrosion or dry cracked wires "

Anyone see/hear of anything like this?

Thanks. Jay
