Everything about this cable
How it works
- Plug the adapter into the ECM and into the base cable.
- Clip the leads to a 12 V battery or power supply and turn on the ignition switch.
- Connect your interface (Nexiq USB-Link, DLA+ or any RP1210 adapter) to the round 9-pin diagnostic connector.
- Open your programming software and work the ECM on the bench, no truck needed. When the software asks you to cycle the key, use the same switch.
