A simple early conversion using a Hattons DCR-8PIN-HarnessMini. Very Important - Both arms of the brush spring must be sleeved to isolate both brushes from track power otherwise the decoder is likely to be destroyed. More space in the tank engine version of the 3F so the decoder has been fixed with a sticky pad to the inside of the body and the smoke unit left in place for ballast only, not powered. Interference suppression components removed. Decoder harness wires are hard wired directly to the motor brushes with loose sleeves acting as strain relief, track power is connected to the decoder from the pickup wire and the solder tag attached via the motor securing screw to the chassis. Unused wires from the connector are cropped and the extra wires at the front of the decoder coiled up. Black tape over the magnet is to improve the cab area appearance.
