These are pre-terminated wire harness pins you need to add PTO high idle to your 1994 or newer 6.5L diesel! Tuned and stock PCMs have this feature pre-programmed, but the wire(s) were not installed from the factory on most trucks.
Benefits :
- Faster warm-up during cold weather
- Enhanced A/C cooling during hot climate idling
- Promote coolant circulation and airflow during cool-down after a hard pull
Idle Speed :
- 1994 and 1995 Trucks allow a single speed via one input
- 1068 RPM
- 1996+ Trucks allow three speeds via two inputs
- 1068 RPM
- 1200 RPM
- 1600 RPM
*Note, all idle and PTO idle speeds can be modified with our custom tunes. The data included here is for stock tunes.
