Factory high beam accessory lead under pod….

I’m looking into possibly installing a LED light bar and I want to use the OEM high beam lead referred to -HERE- and -HERE- coupled with a relay so the LED light bar will turn on/off with the OEM high beams w/o adding an additional switch. Does anybody know where this blue wire is and can confirm it’s existence? I haven’t looked for it yet, but thought I’d ask before I do.

thanks!
