Well I know black goes to a ground and red goes to a 12v positive switch...but how would I go around connecting the purple o2 sensor wire? do I have to dig through the ecu to find the o2 sensor? which one is it?
From 93 wiring diagram, the "OX" wire is white.
You can access to this wire at the ECU, at the O2 sensor, or at the diagnostic port (easiest, if your wire coming out at the driver side).
Thanks, is the OX1 sensor the first one (1) and OX2 the second one (2) that I labeled in attached pic? Excuse my unfamiliarity I am a newbie.
So should I connect the signal wire to the OX1 in the diagnostic box or to OX2 or does it not matter.
