This section shows how to wire a device via the vehicles ignition feed. This applies to the Peugeot Boxer (shown) Fiat Ducato, and Citroen Relay. The vehicle I am working on is a 2016 Peugeot Boxer.
What applications do I need to connect to the Ignition Feed? Firstly you dont have to connect anything, the choice is yours, some people do, some people dont. I will connect two units A) The Sterling Battery to Battery Charger and B) The CBE Control Panel. The reason I prefer to connect to the ignition feed is because I rather these units shut down when the engine is off. The CBE unit is quite intelligent, it understands when the engine is off or on via the ignition feed and thus things like the refrigerator will remain switched on.
Below: Remove the panel near the steering column
Below: Look for the main ignition cable and remove the black insulation to expose the wires
Below: The ignition feed on the Peugeot Boxer or I believe Fiat Ducato and Citroen Relay is shown below. This wire is White with a Black Line it may also be a little thicker than some of the others. Split this wire open with a sharp blade (make sure the ignition is off). Then separate the strands of copper (dont break them) and hook a new wire to them. Next solder the new wire to the ignition feed and insulate with tape. You should have a new wire running from the ignition feed that you can connect to the terminal on the Sterling Battery to Battery Charger.
Below: I am running the new red wire under the panels into the back of the vehicle. It will be totally hidden.
Below: Shows the Ignition feed (Red Wire) that is about to plug into the Sterling Battery to Battery Charge. Different Sterling Chargers may have different locations for this wire. On my unit I removed the “Wire Bridge” which ran across two connections, I’ll call them top and bottom connectors, I connected the Red Wire to the top connector (but check with Sterling Power as your model maybe different).
