I'm having almost the identical issue as kjaikaran had back in 2013. That post can be found here:

Same story as his story, only I'm only installing a remote start, no alarm. Everything is installed, and I, at one point after the install, had access to the programming mode, but now that I need to program the system, I'm unable to access programming mode.
My vehicle is a 2006 Ford F350 Powerstroke, King Ranch edition. I used bulldogsecurity.com and a pdf from directechs for wiring information for the truck. Here's what I have wired so far:

The Viper remote will lock/unlock the truck, but that's about as far as I can get. Any procedural attempts to get the system into programming mode fall short. Here's what I do to try to enter programming mode:
1. Turn ignition on then off
2. Press and hold Control Center button and wait for notification beeps corresponding to menu number
3. Release Control Center button
4. Press and release Control Center button for corresponding feature, press and hold Control Center button.
5. Holding Control Center button down, use Viper remote to program feature.
Nothing at all happens during number 2 from above, no matter how long I hold the control center button down. I've had to unhook the horn trigger wires (brown from the 6-pin, and blue from the 24-pin) from the truck because no matter what I do, it seems that the Viper is sending an alarm signal and the horn blares non-stop. I feel like I've made some mistakes along the way, specifically concerning the door trigger wires. I feel like the Viper thinks the doors are open, that why the horn goes non-stop.
At one point in my life I was a certified mobile audio installer, and I thought this wouldn't be this difficult of a process, but I'm waiving the white flag.
I'm not sure anything I've done here is remotely correct and I would appreciate any help there is out there.
