2015-2017 Mustang

The 4 yellow wires with black stripes will tap into the coil pack outputs at pins 42,43, 57, and 72 on the c1551E plug (the top most plug on the ECU). It doesn’t not matter which of the yellow wires go to which output, only that they each go to their own output.

The red wire will need 12 V+ and the black wire will need to be grounded. There are many ways to do this, including using a make-a-circuit to tap into the fuse box.
