Welcome, I am Chris (aka-Moose)
There are alot of wires that could of been moved or damaged during this repair, so finding what you did based on symptoms alone is next to impossible and the air bag system is not something you want to poke and prod on trying to partially diag and find the issue. Is there anyway you can get it scanned and get me the codes. This will tell me how to help you diagnose this.
