    Nice job on all the wiring and documentation. Someone spent some time doing a bunch of graphics. The power wiring setup looks familiar.

    The only thing I saw that's slightly confusing is there are two wires for the Coyote start circuit. There is the light blue SMR wire from the Coyote pigtail that goes to the RF blue start wire from the ignition switch. Its purpose is to signal the Coyote ECU to initiate the start sequence when the ignition key is turned to start. Then there is the heavier (and separate) start wire in the Coyote harness itself that goes to the actual starter solenoid which energizes the starter solenoid when commanded by the ECU. Saw references to this wire as "SMR" which technically it isn't and could be confusing. That's being really picky but thought I would point it out.
