Wiring

Now that the track-bed is done and the tracks positioned on top of the track-bed, it is time for wiring. There are three activities here:

1. Wiring switches
2. Wiring tracks
3. Drilling through the plywood for those wires

Wiring basics

I use solid color cables gauge 22 to wire switches and tracks. I also use heat shrink tubes to protect the solder between the small wire from the switch and the wire cable. 

I bought the wires and the tubes at Micro Center:

• Heat shrink tubes: https://www.microcenter.com/product/391392/nte-electronics-multi-color-assorted-4-inch-heat-shrink-tubing

Wiring switches

I went through this step in detail in this post here. I'm only putting pictures.

This is for a Peco Double Slip Switch (SL-U8363 Code 83 Unifrog #6). 

This is for a simple Peco Electrofrog Switch.

This is quite time consuming:

Wiring tracks

This is very straight forward. I used either a fiberglass scratch brush (https://smile.amazon.com/gp/product/B002RMCFZM) or a small file to prepare the bottom of the track for soldering.

Then, I use liquid electrical tape to protect the solder - https://smile.amazon.com/gp/product/B0000AXNOD

Drilling through the plywood for those wires

Once all wires have been soldered to switches and tracks, I put them back in place and drill through the plywood. For wires, I use a 5/32 bit for the wires, and a 1/2 bit for the switch motor.

It is time consuming and will probably take a few weeks to complete.
