What Color Wire Is The Reverse Light???

[2007YukonXL]

Hey there,

I am installing some tow mirrors that have LED reverse lights on a 2007 Yukon so I need to find the correct color wire to tap into.

I have ran the new tow mirror LED power wires to the power box on the left side of the instrument panel (this is the location where the wires go to the connector that runs down to the drivers side door sill) and inside this A pillar power box I want to tap into the wire for the reverse lights.

Does anyone know what color that wire is?

Also...my old trailer had backup white lights and that was a nice feature however my new trailer does not have backup lights and I see that the & PIN GMC trailer cable has a yellow wire that is capped off on the new trailer...is this the backup light wire?
