Spark plug wires / ignition cables

From W220 wiki:

  • Spark plug ignition cables have a limited life. The resistance element in the cables often fails or goes high resistance due to fatigue.

Cable lead insulation can break down causing arcing to ground. The resistance for new plug wire is approximately 2.18K ohms.

  • It is possible to perform basic tests on an ignition coil using a digital multi meter (DMM). Each coil secondary resistance measured from the plug cable to any of the three pins in the input electrical connector is approximately 4.8 M Ω (Mega Ohms). The cable circuit is isolated from ground thus the resistance between the cable pin and ground is infinity Ohms or open circuit.

Ignition cables are in different lengths:

  • G-cable: 245mm - A1121500118 (45 EUR), BOSCH 0356912948 (Bosch EE948) (14 EUR) - M112 x8, M113 x9
  • K-cable: 265mm - A1121500218 (45 EUR), BOSCH 0356912950 (Bosch EE950) (14 EUR) - M112 x4, M113 x4
  • H-cable: 290mm - A1121500318 (56 EUR), BOSCH 0356912952 (Bosch EE952) (30 EUR) - M112 x0, M113 x2 (If H-cable is not available, a slightly longer L-cable can be used instead.)
  • L-cable: 315mm - A1121500418 (56 EUR), BOSCH 0356912954 (Bosch EE954) (32 EUR) - M112 x0, M113 x1

Wiring / Electricity

Most modules use TE Connectivity AMP MQS (Micro Quadlock) pins and connectors. Other parts are from KOSTAL connectors.

ECU / PCM connector



Most, if not all, pins use "Locking Lance" type pins, which have a small lip that locks it in place. You have to push this in to remove the pin from a connector or adapter.
