Unplugged wire harness next to power mirror harness

Hey yall. So I’m a dumbass, I removed my speedometer to have it repaired and I didn’t label or take pictures before hand and here I am putting it back together so I’m a little confused.

there is a wire harness paired with my power mirror harness with nowhere to plug into. Trying to figure out if I’m dumb or going insane. Can’t remember if it was actually plugged into anything, and I’m terrible at reading electric diagrams. There are no auxiliary switches next to the power mirror control

pics attached, help appreciated

 

By wire colors I belive that's for Downhill Assist Control, your truck doesn't appear to have a switch for that so it's not used.

 

Thank you, I was thinking the same

 

You can purchase the mating connector and use the illumination circuit to attach it to the illumination of an added switch for an accessory.

 

Thank you so much !
