Brad Burnett Posted May 26, 2022 Report Share Posted May 26, 2022 Lambda sensors of the bosch 4.9 variety can be wired direct to the ecu via the C Connector on thunder. Pins 3-7 would connector to bank 1 sensor and pins 9-13 would connect to bank 2 sensor. C 1 Main Relay + 2 Ign Sw 3 MES 1 4 APE 1 5 IPE 1 6 RE 1 7 Heater 1 8 Main Relay - 9 MES 2 10 APE 2 11 IPE 2 12 RE 2 13 Heater 2 Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 26, 2022 Report Share Posted May 26, 2022 Yeah I would guess from the documentation you have been given that your loom is only connected to the A & B plugs on the ecu. Lambdas are wired to plug C so I would say your loom probably doesnot include the lambda wiring. Quote Link to comment Share on other sites More sharing options...
