Problem Adding powered/heated seats

[Chiefet]

I have a 4th gen Ram 2500 tradesman. I want to put in powered heated seats, so I bought front powered heated seats, and rear heated seats. I also am replacing the jump seat for a center console even though I have the floor 4-wheel drive shifter. I'll cut a hole to let the shifter through. I got some awesome help from Mr. Grimm and purchased the necessary harnesses. I removed the old seats as well as the rubber flooring because I'm installing carpet. That also made running the new harnesses easy. After wiring I temporarily placed the seats in to test before I lay the carpet. I reattached the battery and the truck didn't make a sound. I tried to start it, turn the key and nothing, no noise, the 8.4 screen, or dash lights won't come on. When I open the door, the interior lights come on and the seats actually work when I press the controls on the side of the seat. The headlights also come on when I turn them on. I have disconnected the battery and I'm here asking if anyone can give me some pointers, thanks, ET

PS, I havent added anything to alpha OBD yet

Mr Grimm swiftly got in touch with me and told me to go over all of the connections and make sure they were tight. I immediately found the heated steering wheel connector (i311) wasnt locked in. locked it in and everything worked prefect
