vehicle.

Hood Pinswitch
The Mercedes Sprinter does not come with a factory hood pin. One can easily be added and tied into
the Smartkey Starter®. This should be done for your customer’s safety and is highly recommended.
This connection is not required if an alarm controller is used. The hood pin can be directly connected
to the alarm controller without the relay described below.
1. Mount the hood pin and confirm its operation.
2. Route the hood pin wire through the firewall to the under dash area.
3. Locate the brake pedal switch. Using a relay, the hood pin will be tied to the brake in order for the
remote start to shut down when needed.
4. Connect the hood pin wire to terminal 85 on the relay.
5. Connect the brake wire to terminal 30
6. Connect the ignition wire (from the brake switch supply) to terminal 86 and 87.
Using this connection, if the hood is opened and the ignition is on, the brake switch will be activated
and will not allow a remote start situation.
