Ok, I have two quick questions:

The instructions aren't very clear on where to connect the O2 and Ground to my ECU. (I have the APEXi TT) What wires should I be tapping into?




Also, here is the pesky two extra wires coming off the harness. Red is for 12V+, and Green is for the Ignition... but but but - - this seems redundant! The harness already has connections for 12V and IG1. Do I need to connect these or are they just a bypass if the harness doesn't fit my car?

 

The FSM will tell you...

i have the fsm, but im having alittle trouble udnerstanding the diagram for the ecu. im really bad when it comes to reading electronics diagrams..

 

OK, it shows the plugs as if they are plugged into the ECU.

 

heh, ok, i just figured out that what i was looking at was the damn cruise control

am i correct in thinking ECU = CPU? this is still stupidly confusing

 

Yes, ECU....
at the base of the firewall of the passenger side of the vehicle...

 

its on the passenger side? everywhere i see in the FSM shows it on drivers side left under cruise control

 

ok, this is quite retarded...

on page 33 of the FSM it shows a CPU diagram, but nowhere does it mention O2 sensor.

the instructions are really blurry where it shows what my CPU harness 'should' look like, and where the 02 and grounds are, but it's not clear at all.

anyone know what color wire is the o2? is it the yellow one?

 

read my previous post, you're looking for the ECU not the CPU. The ECU is the engine control unit, the CPU conrols the lights, gauges, things of that nature.
