Are all 3 wires still attached to your corner lights? I believe the red wire is the wire that keeps the corner lights on with the headlights, and the green wire makes them blink. Check where the splices were on the red wires to make sure they are still conected everywhere.

What did you splice with? Wire taps or did you actually cut the wires and splice them with 2 wires comming out of one?

Why were you un-splicing wires with your battery still connected?
