If you want to have a look at my Annie installation, just click on the following link. There is a lot of useful information there.

I cut a platform out of styrene sheet and mounted it above the speaker and around the Bachmann sound card (chuff only).
 

 
My homemade NiMH battery packs were fastened to the sides of the platform with cable ties. The receiver is mounted on the back.
 

 
Only the rear light wires are attached to the shell. Everything else rides on the frame which is great for testing.
 

 
I hot glued a styrene bracket to the top of the battery holders to hold a Black Kat antenna. With it and a telescoping antenna on my transmitter, I get at least 100 feet of reliable and responsive radio range. Noise suppression components are not required because the receiver is isolated from the motor.
 

 
The two black, 2-pin plugs are used for charging. They are easier to mount than jacks and won’t short. I get better results charging my battery packs separately than others have charging them together. The original Bachmann white, rear light plug now passes power to the locomotive from the receiver. The rear light is attached to the rear lighting circuit of the receiver and can be used for programming. The other white plug is for the sound cam in the locomotive.
 
If the female portion of a 2-pin plug is used for charging, the wings can be removed to make it less obvious. Here is the charging plug for the lithium-ion battery pack in my NW-2 hanging on the pilot.

All the wires in the Annie for motor, headlight and rear light MU plug are joined with loop connectors on two posts. I had to take mine apart to find that out. This allows the rear light MU plug to provide power from the tender to the motor and headlight.
 
The Large Scale/NMRA switch at the front will reverse the flow of track power when toggled. This is accomplished by soldering the track power wires to the tabs on one end of the switch along with jumpers to the opposing tabs on the other end of the switch. I guess this gives the Annie the flexibility to run in the same direction as any other locomotive no matter how they are wired.
 

 
I unsoldered the wires from the tabs on each end the switch to isolate the track power pickups. The remaining wires on the center tabs of the switch must be attached to those previously mentioned posts to power the motor and headlight when using track power.
 
If the loop connectors for the just MU plug were removed from the posts and wired to the tabs on one end of the switch; that should provide battery power to the motor and headlight when the switch was thrown that way. If the track power wires were soldered to the tabs on the other end of the switch; that should provide track power when the switch was reversed.
