CNJ 4-6-4T engine: routing all the LED wires.
There are 2 head lights, 4 marker lights and 2 running board lights so I had to route 16 very tiny wires!
Installed the 'brakes shoes'; having this option on an engine in 1969 was pretty 'fancy'!
'Heat shrink' tubing cut in short pieces for flexibility on the 'smoke box' front; Headlight and 2 marker lights.
Testing at all steps.
Ready to route through the boiler.
Some 'slack' on this end in case I have to do some PM.
A longer piece of 'heat shrink' tubing is taped to the top of the boiler.
The 'running board' wires were also routed to the top of the boiler.
Just enough room for the TCS 1517 decoder.
'Keep alive' at the back of the 'tank'; inserted the frame with motor to insure everything 'fits'.
Wires for the 'tank' head light and marker lights, also, has multiple pieces of 'heat shrink' tubing. Will protect the wires plus 'black' will be less visible from the cab.
All wires routed to the decoder area.
Final test with the 'signal tester'......
Tomorrow the decoder wires will be connected to all the LED's.
I love retirement; everyday is Saturday and I can work 8 -12 hour days on my hobbies
