e-brake and turbo timer problem

[apluc]

I installed my apexi turbo timer about a month ago with the wire that supposed to go to the parking brake grounded with the black ground wire, and a couple decided to connect it to the parking brake as it should be. So I took the wire and spliced it into the ebrake wire under the center console; however when I take the key out and release the emergency brake the car stays running and doesn't shut off as it should. I also noticed that my emergency brake light in the gauge cluster is not lit when it is engaged. I searched and found that many people had a problem getting the light on but found no one who's light would not come on. Has anyone else had this problem or have any ideas as to what could be going wrong with the brake wiring? Thanks in advance!
