No horn

[Doozy]

Hello all I recently did the head gaskets on my 07 Sierra 1500 sle new nbs and it runs and drives great idles fine but the service traction control and the stabilitrak messages pop up and I have no power to the horn or the buttons on the wheel, totally possible I didn’t plug something back in or missed a ground ( I have the cluster ground, battery, and ignition coil grounds all hooked up), now I did start the truck with the headers straight piped to see if it would start and I was chasing a vacuum leak (ended up being the intake manifold gasket) and I might have fried an 02 sensor or both if that’s what running only the headers does, any help appreciated
