How do I install a leviton 5245 combo 3 way switch/outlet

SOURCE: Installing a Leviton 5225 switch with outlet.

A switch is wired using the hot wires only, the black wire. It is simply a break in the line so that when the switch is off no power flows and when the switch is on the power does flow.

You are correct that the middle outlet would have two black wires and two white wires.

If you want to tap into that middle outlet and run power up the wall I suggest you look into some wiremold products. Go to their website, or any home depot and check it out. Get back if you think I can help you further. I am an electrician.

The neon lamp inside of the switch draws very little current (milli, or mico amps) so there is no significant current flowing to ground.

As for your real question, there are several various types of 3-way pilot switches:
Load on: Pilot on
Load off: Pilot on
Some 3-way pilot switches have an external lead which allows them to be configured either way.
If both of your switches are the same type and are wired correctly, they should work the same.
If you suspect that one is defective, try swapping them.
