Trying to install a resister switch in a 1999 buick le sabre... Help a single mom get back and fourth to work!?

I am trying to have my father install a resister switch in my 1999 buick le sabre because the security light stays on and the car refuses to start at times. I am unsure of which wire it is supposed to connect to. I was told two white wires but can't locate them. Can anyone with experience help me out?
