11. If the tender is equipped with an electrocoupler, connect it to the LCRU using one of the

supplied connector wires and a wire nut.

12. After completion of the tender wiring, remove the engine boiler from the chassis.

13. Remove the wiring from the E-unit to the motors by unsoldering the connections at the motor.

14. Unsolder the E-unit connections to the headlamp, smoke unit, and pickup rollers.

15. Remove the E-unit.

16. Layout the 8-pin connector assembly over the engine chassis, noting the wires and their

respective destinations. Note that the motor connections have the shortest wires, and the

connections to the headlamp and smoke unit have the longest wires. Make sure there is
