My vote would be yes.
If you had a previous build with SMB that used the Surepower 1315, they probably already have a wire that is attached to that circuit. They did change it up at times so you will need to check that it has 12 volts only when the key is in start. (Note: They have been know to wire it to the line that is Hot in both start & run)
If not, or your wire is wrong. My 2004 Books say that the start circuit on the key switch connector C250, the switched power to the start solenoid is WH/PK. It should go to your fuse block F2.33 (Starter Relay Diesel), Digital Transmission Range Sensor (Except Diesel). Also F2.27 is for Radio. (Start Cut Out), this goes to PIN 3 (RD/BK) on the Radio Connector.
