	Electrical diagram ARZ to AUM lambda « on: May 17, 2024, 02:46:27 PM »

Hello,

Could someone please provide me with the electrical diagram of the lambda harness to ECU for these VINs?

I'm trying to understand the issue with my wideband conversion, and I need to modify the harness I have because it's a US model and according to the seller, US models are not wired like EU models.

Narrowband: WVWZZZ1JZ1W220173
Wideband: WVWZZZ1JZ1W320820

For 4 PINS (Narrowband) to 6 PINS (Wideband) conversion:

ECU -> 51    -> 4 PINS -> 3 -> 6 PINS -> 5
ECU -> 70    -> 4 PINS -> 4 -> 6 PINS -> 1
ECU -> 5    -> 4 PINS -> 2 -> 6 PINS -> 4
+12      -> 4 PINS -> 1 -> 6 PINS -> 3

ECU -> 52 -> 6 PINS -> 6
ECU -> 71 -> 6 PINS -> 2
