This installation of TCS T1 Decoder is for HO Scale Tyco Alco Century 630 Locomotive and was performed by Thomas Gosser, Big Lake, Alaska

Locate on the sides and bottom the tabs of the truck mounts. You will need to gently spread the locomotive shell apart at these spots to pop the tabs out.
The trucks themselves can be be removed beforehand to make removal easier. The rear truck mount only needs to be removed if you plan on installing a
rear headlight.

 

The front headlight copper mount and wiring will need to be removed.

 

Disconnect the rear truck power lead pickup wire. Remove phillips head screw to do this. Set screw aside, we will reuse it later.

 


You will need to cut the three leads as indicated. Also remove the screw ( circled ) that connects the motor brush to the left wheels power pickup.
Set screw
aside, we will reuse it later.

 

Solder the cut leads to the harness wires as shown. If you plan on adding a rear headlight solder it and any necessary resistor to the lead pointed to by the
arrow and to the yellow harness lead. Make sure it is long enough to reach the rear of the locomotive.

 

Solder the Gray and Orange harness leads to the left and right motor brush leads respectively. Carefully bend the copper tab back in on itself toward brush.

 

Connect a micro eyelet connector to the Black harness lead and fasten it to the left power pickup point using the screw you removed earlier ( circled ).

 

Run the right power pickup lead ( and the rear headlight lead if you are installing one ) back under the locomotive weight/fuel tank and reconnect to rear
truck. Reinstall rear truck into truck mount. Reinstall headlight/mount as removed and tuck in wiring harness and decoder as shown. You can use double
sided mounting tape to hold the decoder to the inside of the carbody. Reinstall front truck mount and truck as removed. Make sure all wiring is out of the
way and make sure trucks oscillate freely within their mounts. Test your installation and enjoy!
