Need help with 1998 Dodge Ram door locks. Finished install of new alrm system.

The truck has a 3 wire harness for the door locks. Both the lock and unlock wire register pos. when at rest and negative when active. I tapped into these leads with my alarm leads, nothing happens.

Do I need a relay, or is a relay only required for a 2 step function?

Willie

If your truck came with keyless entry from the factory then you need a positive trigger for lock and a 5-wire for unlock. This requires the use of at least one relay depending on the make and model of the alarm system you are installing, two relays if your system does not provide a strong enough positive trigger output. You can find the information for the 98 Ram here. The door lock relay wiring diagrams can be found here on the12volt.com

NOTE *1 Vehicles WITHOUT a FACTORY KEYLESS use a TYPE C Door Locking System and Vehicles WITH a FACTORY KEYLESS use a Chrysler 3/5 Wire Door Lock System, to connect, See DIAGRAM. "EXTRA NOTE" on some KEYLESS ENTRY SYSTEMS, look for a ORANGE / BLACK and a PINK/BLACK these wires may work as a TYPE A Door Locking system.
