I am getting ready to install a Code-Alarm CA645 alarm on a 04 Dodge Ram HEMI and was wondering if anyone had installed one of these alarms before.  I have a copy of what seems to be a correct wiring diagram. 

Any info or suggestions would be greatly appreciated. 

Thanks

hey i just did one a week ago it had a black key with no transponder but wat i did notice, when you RS the abs light would go on then once u key take-over it goes away. I didnt use tach. I set it to voltage sense with 0.8 sec crank  n it starts every time even when it is really cold.  good luck n happy new year.
