Particularly in the 90’s, Mercedes Benz used wiring looms that did not stand the test of time. Heat of the engine causes the insulation of the loom to perish. The outcome is an engine that is not running well, and in a worst case scenario electrical components can be damaged through a faulty wiring loom.
Lichtenberg Classics is offering an overhaul for your wiring loom or throttle body.
