Or, you can make your own harness by splicing the computers directly to the engine. That gets really complicated because the power bus is shared, the ground is shared, the relays are shared and the fuses are shared among multiple devices that have nothing to do with running the engine. The Powerstroke is completely integrated into the vehicle and the T444 was designed to be stand alone for medium duty and stand alone power applications. The OBDII requirement is what complicates the Powerstroke.
International makes it easy to run the 444 outside of the vehicle. The engine is self contained with the PCM/IDM wired into and installed on the engine. With the Powerstroke you have to replicate the whole under dash wiring to make the computers work. All of the wires run in the same harness for the engine and all other electronics. It took about two months of spare time wire tracing to make everything work. You MUST HAVE the wiring diagram from Alldata or Ford to make it work.
There are about 40 wires in the PCM harness. There are about 20 in the IDM harness. Each wire in the PCM loops to a sensor and back. On the way, they go through relays, fuses and through three separate wiring harness segments. Each wire has to be traced through each harness wire for wire. There is a power bus with multiple devices on each segment. Each extra device has to be shunted and/or grounded. You cannot just send power to the PCM and make it work. It works as a complete system.
It is not that easy. You have to wire the PCM and the IDM. We took all of the wiring harnesses and spliced them wire for wire to make it all work. It took a while to get it working. We can scan and monitor each sensor just as if it was in the truck. We are working on a custom harness that will make the right connections quickly and easily without all of the extra wires.
Correction: The PCM harness has 104 wires.
