Question Changed stereo, functions not working

So last night I installed a double din kenwood stereo. Everything with the stereo works fine but when I got in for work this morning the memory seat didn't slide back into place and when I started the truck the 8 way seat functions and heated seats did not work. Then when I went to press my horn that did not work either. When I got to work I fiddled with the cables under the seat it magically started working but was sporadic and wasn't the normal slide into place. (this is also just the driver side didn't have time to test the passenger)

I also didn't install the chime box because I hate when the chime sounds when the door is open and that sort of thing but would it really make my horn not work or did I just unplug something when putting the dash together?

Yes, it sounds like you just unplugged something. The horn an be controlled by the BCM computer but it also has just a simple parallel switch going through the turn signal arm connector that does not rely on the computer. Autozone has free wiring diagrams which would allow you to start tracing where the multiple problems are.
