CanTrol WC output plan
What each CanTrol WC output feeds, its rating, and which slide position or button turns it on.
Ratings and pinouts are from the Whelen CanTrol WC Installation/Operating Guide, form 14580G. Every output is set to steady on/off, because each light runs its own flash patterns. The light bar wire functions were confirmed on the bench on 2026-10-11. Nothing on this page has been tested in the truck yet.

Power and inputs
Section titled “Power and inputs”- Main input: 80A max through two red leads, each fused 40A at the battery, and two black grounds. 12V DC ±20%, negative ground only.
- Ignition sense: J17-7 (red/white).
- Left unconnected: horn ring (J17-1), Park Sense (J17-2) and backlight (J17-5). Backlight brightness is set in Whelen Command instead.
- Estimated load: about 9A worst case with everything on, well under the 40A combined limit. This is an estimate, not a measurement.
Open items
Section titled “Open items”- Confirm the module model on its label.
- Confirm Whelen Command shows the brake and Park signals for the 2017 F-150 over the CANport.
- Check whether blank button 1 stays latched after a restart, and how long the system stays on after the key is off.
