You cannot use a Curt Q or A Series fifth-wheel hitch, PullRite SuperGlide fifth-wheel hitch, Reese Trail Boss fifth-wheel hitch, B&W Companion fifth-wheel hitch that mounts in the Turnoverball gooseneck... view full answer...
Hi Diane,
I've attached the video Sam referenced below, but I will say that Ryan kind of skips over splicing the harness into the factory wiring so I found a video I made for another stereo where I'll walk you through this process starting at the 5:20 minute mark. I've attached the wiring diagrams for both the Jensen # JWM60A and AWM970 to help with swapping over the wiring. If you still need help then let me know and I'd be happy to help out further. view full answer...
