NGC or GPEC2?

Finally (mostly) past the 5.9 swap into my Dakota and sold the harness and JTEC I built to do a Magnum EFI swap so started working on the PDC for my G3 swap. Discovered a couple of things in regards to the differences between an NGC and GPEC2 controller and thought I would post them here in case it helps anyone else.

The NGC controller does not have a radiator fan control function, much like the AC control mentioned earlier. The fan and AC are controlled by another module connected to the front PDC. So, the control of the fan will need to be done via a separate module much like AC will.

In comparison, the GPEC2 does control the fan to a degree. It has a control circuit, but in an LX/LC car, the non-HC models have a low and high speed fan and the function of turning those on and off is controlled separately. So a GPEC2 controller could turn a single radiator fan on and off, but if you wanted to run the OEM dual fan setup, it would require a separate controller.
