Yeah as you found out should have used the provided hardware. The instructions they sent me too were also out of date but I only did the front seat Jackers so was pretty straight forward
im not too familiar with their product, i have used others with a push button start and factory fob. does this one require you to send the unit back to them for more programming?
I would go whatever way makes sense to you, personally i have not much respect for dealerships. i have put deposits down before only to show up and they vehicle has been sold to someone else. i have ordered a vehicle and once again, watch it go to someone else because i was at work. they wont...
glad you got it sorted out, on newer fca vehicles if they are halogen bulbs from factory it expects to see that amount of power draw and when its less like when you install LEDs it things there is a issue and turns it off.
