Car Alarms: keyless entry, resistance levels, door locks

Question
I have an 2007 dodge charger my wife bought me a freedom 400 alarm with keyless entry, I bought the interface DM-1 but i can't find out what type of door lock systems comes on the car, i was told that with the new chargers and magnums you have to install a bypass... If this is true where can i find one

Answer
These are single wire negative resisted door locks.

You need to use an OHM meter to determine what the resistance levels
you would need to make it lock and unlock.

See www.relayhelp.com and look at the relay application
"single wire negatives" .

Good luck.
