My 21 1500 custom has a violet wire on this plug. Is that it?

I just tried tapping into this wire and it did not work. Which wire can you tap to make accessory lights come on as described?

I bought tow mirrors from real truck. They look great easy install. I was under the impression the plug and play would allow me to gain directionals. I did not I have the 3 wires that came with the mirrors (white,blue,orange) for each side. Now I have the correct wiring procedure but it's the pins I need to know what size to use. (The pin connectors)I have a box from Amazon (twippo) with a mix of sizes anyone know which size works for the harness boxes? I know I have to jump the 2 boxes under the dash after to get the cargo reverse lights. I just need to know what size those connector pins are I belive I need 12 one for each end that goes into the mirror plug and the other one down on the lower door/body. Anyone know what size these are?

I am trying to add footwell lights to my 24 1500 XT4, what is the dome light pin?  I am also looking for the running light control as well, I want to put an accent light under the dash that is connected to the running lights as well.

 

I was also trying to access the link to the Upfitter docs and I cannot view anything, it doesn't let me open any docs.
