2013 mustang v6 standard key fort1 evo all wiring ?

Question

diagram has me confused on power source.  Guide 70291 shows brown white from 20 pin going to a relay and then wiring running to purple white on wiring harness for park lights with a 10amp inline fuse added.  im scratching my head confused.

ive got my gray and gray/ blk ready for can, I've made my lt blue , lt blue/ blk, yellow connections , got my dark blue from 20 pin ready for override switch to be grounded, so I think getting power to it is all that is left and I'm just in a fog on what to do with brown/white from 20 pin to park lights

Answer 1

Brown/white is switched negative from Evo and will connect to relay coil side with always hot positive on other side of coil. Purple white will be on relay switch side with always hot positive on other side of switch.
