multiple electrical issues
 

All these happened the same day apparently while I was replacing the spark plug wires on an '02 Taco.

1)electric door locks only lock when ignition is completely off. While on/engine running the locks "jump" to the unlocked postion, will not lock when I shift to drive or use the door swithces.
2)Reverse cam on the AVICD3 will not cycle on
3)the front cabin reading lights wont cyle off, even after the vehicle is shut down or shift into drive (had to take the bulbs out).

Previously i noticed the remote start on the alarm stopped working.

could some or all these be related.
