Dude. This is more of an accomplishment than you give yourself credit for.
I've moved from an Accord to a Bullitt (and then wife's F150). The buttons programming on the Fords is a PITA compared to other "homelink" systems. Or I'm just an idiot. Probably both.
Don't beat yourself up...the instructions in the Ford owners manual suck!
I'm an engineer and must have read it a dozen times and it still didn't work so I shelved it for a week. Decided to try a different approach and looked up my garage door model to see what they had as an instruction. Sure enough, Lift Master had a procedure to program......this was very simple.
I only needed steps 1 to 4 below and it worked. I didn't even need to hit the learn button on the Lift master unit. You may want to see if your garage opener has similar instructions from their site.
