NEED CCRM Wiring Diagram 1998 Mustang GT

If anyone knows where I can find or if they can email the wiring diagram/schematics for the CCRM on a 98' GT I'd really appreciate it.

Thanks everyone!

To the best of my knowledge there isn't a single "diagram" for the CCRM. The CCRM is noted when it is part of a sub-system. For example, engine controls, AC, Cooling fan, and the like.

There is a diagram for the CCRM connector. However, it does NOT tell you what the individual wires do.

Do you have a particular question you are trying to answer?

Yes... Engine Compartment Fuel Pump fuse continues to blow and I need the CCRM wiring diagram/schematics to know all the wires leading out of the CCRM to see if I can find a short. I have disconnected everything individually that is connected to the CCRM and the only time it does not blow is when I disconnected the CCRM. If there is another reason why it would continue to blow let me know. It's been 4 months now and no one has been able to help and I'm tired of driving my secondary car.

Tell us about any mods or other work.

For the 96-98 MY, there are multiple sub-systems powered from the PCM. The PCM fuse will blow, but the problem is not in the PCM or the CCRM.

The fuses stop blowing when the CCRM is removed becuase this stops the power to the PCM. This is like throwing the baby out with the wash water.

The usual place to look is the O2 heater circuits. Any work on the rear O2? New exhaust? Have you tried disconnecting all 4 O2 sensors?
