it might sound like a redundant question, so I apologize in advance: Do I need to have Innovative controller to connect LC2 O2 sensor to ECMLink if I'm not using a gauge? Can I connect it straight like this:
RED wire -> 102 or 107 pin SWITCHED 12V
BLACK wire -> 101 or 106 pin GROUND
YELLOW wire -> 4 (or 15, 16) pin SELECTED ECU INPUT
The controller is required for the gauge to operate, isn't it?
