Would this happen to be it?
Thank you for the help, truck does not have lights on the side fairings that's what we would like to install but this definitely has gotten me...
Found the wire in the sam cab purple and white connector X3 and 7 just don't know where it is ran after the sam cab
Last six of the VIN is FJ9756
Have a 2013 Cascadia, Purchased last year does not have factory mounted work lights on the back at all but has the utility light switch in the cab...
