Verified MY26 Roof-Outlet Map
| Switch | Roof outlet assignment | Published circuit |
|---|---|---|
| EXT2 | Front right | 25 A circuit A |
| EXT3 | Front left, rear left, rear right | 25 A circuit B, shared |
This map is model-year specific. Compare the handbook, fuse information, and harness fitted to the exact vehicle before connecting a load.
DTP Connector Capacity Is Not the Vehicle Circuit Rating
TE Connectivity describes the DEUTSCH DTP family as a size-12 power-connector system with up to 25 A continuous contact capacity and a typical 10–14 AWG wire range. The usable vehicle load is still limited by the Grenadier circuit, wiring, connector, environmental conditions, and the connected equipment.
Plan the Shared Circuit
Add the current of every device on EXT3 and keep the combined operating load within the documented vehicle circuit. Use the device maker's inrush and continuous-current data. Do not assign 25 A independently to each of the three EXT3 roof outlets.
Connection Checklist
- Confirm the vehicle model year and auxiliary-switch package.
- Identify EXT2 or EXT3 with the current handbook, not wire color alone.
- Use compatible connector bodies, contacts, seals, and the correct crimp tooling.
- Protect and route the accessory harness for abrasion, water, heat, and strain.
- Test polarity and operation before connecting the final device.
Owner Reality Check
Does anyone have a diagram on what switches control what extra wires?

Read the cited owner discussion. Owner reports identify practical questions; the OEM or product documentation establishes specifications and procedures.
DVA Plug-In Options
The Starlink Mini DTP cable is a current plug-in option for a compatible available DTP port. For lighting, review the DVA Side Flood Light and the DTP cable collection. Confirm the combined vehicle-circuit load before adding devices.
