2001 Toyota Sienna
Hello,
I am trying to install my Wide Band Quad EFIE to Toyota Sienna 2001. As I understand Sienna has two Wide band sensors - AFR+ (Brown wire), AFL+ (Blue wire) and one Narrow band sensor - OXS (white wire).
So, I need to connect Brown and Blue wires to EFIE (wideband connectors) without cutting, and I need to cut and connect White wire to EFIE NB sensor 1 connector, and return white wire from EFIE connector to ECU.
Is it correct? Could somebody help me with that?

Thanks.

You are correct. Use a lead wire that is tapped into the wide band signal wires. This will let the efie add mA to the signal making it richer. Cut the downstream wire. The efie adds mV to the signal wire this way.
