no it is missing the brake trigger you will have to tap into for that. so its black with green strip goes to the trailer yellow with red strip 12v power and white is ground.

#1 jumped brake to ground at the plug #2 wires under dash #3 checking for ground on the black/green wire #4 show 12v at yellow/black wire (excuse the spelling) #5 show ground at white wire

just need to order a controler ill let you know how it goes.

so the black and green got the back trailer brake pin. the yellow is 12v power and the white is ground. just checked with meter. just have to find a brake triger off the switch and be ready to go.

have you verified what those wires are for?

so i looked and there is a wire for brakes on the 7 pin i have followed it up to the engine bay then i loose it. looking at the owners manual it has fuses for trailer brakes and a trailer module. not sure where any of this is still trying to find that.

I just pick mine up on Thursday and will look when I get home from work.
