Gen 4 Coyote Wiring Questions

[Papa]

I still don't have my engine in the shop but continue to plan out the wiring connections while I wait. Most of what I'm seeing is very straight forward and I've created a document for what I have planned:



I have two questions that I am still unclear on. Anyone that has installed a Gen 4 Coyote have any details on the following that they can share:

1. Fan wiring? I see a control wire in the Coyote harness that I assume I can run directly to the fan or to the RF relay to allow the Coyote PCM to control the fan. My question is whether there is a preferred method and a secondary question is what to do with the A/C fan wire in the FFR A/C wiring harness? I see that one of the RF Fan Thermo Control wires goes to the trinary switch, so that leads me to believe I should be controlling the fan through the RF fan relay. What is the purpose of the fan wire in the A/C harness where the power and ground wires are?

2. The MIL for the Gen 4 looks like a light that is provided alongside the OBDII connector. There is no ground wire in the IP pigtail for the MIL like I see in some on-line references. Can anyone explain the MIL setup with the Gen 4 control pack that FFR ships with the engine? I'm looking for a MIL (-) wire that I can connect to my Dakota Digital gauges to light the check engine lamp in the gauge when the Coyote signals the MIL.

Thanks,
Dave
