## Mercedes OEM Engine harness layout (ME2.0/1/8)
This is helpful information for swapping or building your own "improved" Engine Harness.
ME2.0/1, (Roughly MY96/7 to MY99), the stock ECM for a Hellen128 system will have 2 plugs for E/F in the ECM, and then a handful of other plugs depending on chassis.
W210 chassis will have 210 545 81 28 (Black Strip Plug), R129 will have 029 545 72 28 (Green Oval Plug), W202/208/170 may have both. In addition to the Engine Harness, most cars with ME2.0/1/8 ECMs also have rear mounted batteries, there will be a bulkhead connector on the firewall which connects to the starter; these cars will also have 722.6 Transmissions, which have a 13 pin connector on the right side of the transmission.
The strip or oval plugs connect a handful of accessory sensors, power leads, and the starter wire. *In General*, on a MB wiring harness, plain brown is GND, plain red is +V, purple is starter circuit.
