Thank you for the rapid response, the wiring and diagrams are not that daunting. My source of unknown is if the cab is prewired for a radio, even if I chose "no radio" in my options?
Long ago post, but curious how your install went. I am awaiting a 2610 and curious if the cab is prewired or not. At $700 for a radio, I thought I could find as nice of a head unit and install myself for less than half of that.
