Here is a web site for free wiring diagrams . http://www.bbbind.com/free_tsb.html Enter your vehicle info. Year , make , model etc.... Then click engine under system ,then charging system under subsystem . Click the search button , then the second blue link . This is the starting system wiring .

Electric Testing Techniques You Need to Know
SOURCE: car alarm preventing car from starting
1999 CONCORDE: check the battery terminals probably they are not tight enough...something like that happened to me just the lights turned on and the car seemed to be dead, the battery is still ok since then. I just needed to buy new terminals.

If it just clicks when you are trying to start, the battery is low, near dead and needs recharge or replace.
If it starts and strange clicking continues, it is a sign of hydraulic valve lifters not functioning properly --which can be caused by low oil pressure (because of low oil level or bad oil pump). If the battery is good and drains dead after a while --something is connected that should not be. Even your dome light can do that --or the headlights on --or the parking lights on. Check the oil level, if low, add oil and check again.

SOURCE: My 98 Monte Carlo won't start. The lights, radio,
check the fuses there is a starter fuse, if not check the starter for power at the small wire if no power could be the relay,if you have power at the small wire its the starter that's bad.
