diagram
Hey, do you have the wiring diagram for a 97 bird for the upstream O2 sensors? Specifically one showing the routing from the PCM to the sensors and back to the PCM. Trying to hunt down a problem in the heater circuit.
Thanks,
Gordon

Might also want to post the bulkhead connector in the engine bay. Makes it easier to track down shorts.

I always wondered if there were any differences in these plugs; I'll find out, lol.

If anybody has a pic of this connect, I will get you a diagram.
I'm not sure which connector or what it looks like...

Anyone know where S283 is located in reference to the O2 sensor diagram?

Here is the power supply for the O2 Sensors from the CCRM:

Thanks again Rick! This is a huge help in finding the needle in the haystack!

The main connector is the same on all 104 pin EEC V connectors but the cap on the wire end has holes plugged for the unused pins that need to be drilled out if doing a repin
There are no differences I've found between 96 and 97, which are supposed to be the same. :)

I've added the knock sensors and imrc wiring to all the cars I've had that far apart; before learning the knock sensors sux. IMRCs may not be required either, lol.
IMRC control may be enabled in the eec and it will work, but the eec output (for our cars) has no drive capability; you have to roll you own driver for the actuator.

:D

My 04 Mach 1 EEC harness has an F5 part number etched into the EEC connector. That pretty much says it.


The Marauder/Mach 1 PCMs hardware is supposed to be much better for utilising knock sensors BTW.

ooo, i was just looking for the pinouts on that bulkhead connector! is that the same for the 95 as well? i was kind of hoping to compare and contrast before i swap over my 96 engine harness, just to make sure.

thought i had these pinouts in my chilton manual but i cant find em >.> just the ECMs for all years and engines.

C161? Different pinout. In fact the connector itself is the opposite, as it ends up Female - Female if you're trying to pair a 96/7 engine harness to a 94/5 EEC harness.

that's what i thought, i was looking and noticed all the wire colors were different and the connector itself didn't line up right. but i assumed that was because of the different placement from the two years.

guess ill be swapping the whole ecm system and rewiring the floorboard connectors afterall. kind of didn't want to have to drop the trans pan for the TCC so soon >.>
