This is going to be way outside the scope of a normal inquiry. My 2004 Ranger FX4 Off Road started having a brake system problem where the rear wheels would intermittently lock up on light braking. There was no ABS light on the dash. To make a long story short, I finally found a C1186 code deep in the ABS DTC. Following the Ford diagnostic procedure in the shop manual, I found that the problem was in the CM. Ford no longer produces the CM and the used one I purchased to replace it had a critical fault in it as well. With parts not being available to repair, I embarked on another option. In my local wrecking yard was a 2011 Ranger 4x4 Sport. I collected the entire ABS system including the complete rear axle assembly. I also collected the complete dash with wiring all the way to the back if the truck, steering column and seats. I did not get the ECM or the engine compartment wiring harness do to the condition of those parts. I have located a NOS engine compartment harness and I can get the 2011 ECM from Ford. The physical retrofit is not a problem for me. The problem is how do I get the components in the system to talk to each other. I understand that the first time I restore power to the vehicle, the will be no Vin in the PCM, everything in the engine, transmission and doors will display the 2004 Vin while the ABS HU/CM, the SRS system, stability drive system and the radio will all have the 2011 Vin. How do I get all of the proms in the system on the 2004 Vin so that they will all communicate?
