tbc Posted April 23, 2023 Report Share Posted April 23, 2023 I'm confused with the conflicting data searched. How do I connect LSU4.9 to the Loom B? Don’t want to risk frying the ECU. Under the wiring information in the Help section it indicates the below wiring colours. APE Sensor Red Wire (pin 1) IPE Sensor Yellow Wire (pin 2) Heater Sensor White Wire (pin 3) Ignition Switch Grey (pin 4) MES Sensor Green Wire (pin 5) RE Sensor Black Wire (pin 6) In the Fury Quick Start guide, below colours excluded the grey wire. MES Sensor Green Wire (pin 5) RE Sensor Black Wire (pin 6) Heater Sensor White Wire (pin 3) IPE Sensor Yellow Wire (pin 2) APE Sensor Red Wire (pin 1) On the actual LSU4.9 connector side, I see Black, white, grey, yellow, and red but not green.

Adamw Posted April 23, 2023 Report Share Posted April 23, 2023 Both are the same arent they? Just grey is missing from the Fury quick start guide as that wire doesn't connect to the Fury, it goes to the Ign switch. The sensors dont have a green wire, pin 5 is the calibration resistor inside the connector. You dont specifically need to use green as a color, but you do need to connect Fury MES to LSU5. The colors are just Bosch's convention. Quote Link to comment Share on other sites More sharing options...
