I have a Flickering Fire Box from a Lionel Flyer Y3 and was wondering if anyone knows how to hook it up to use in a different engine. It has a 3 pin plug and one pin is marked GRD and another is marked J1 but the center is not marked at all. I looked at the wiring diagrams and it just plugs into the BEMC but no idea where it goes from there. Does anyone have an idea how to make it work out of the BEMC circuit?

The BEMC generates the signal to do the flicker with that PCB. To use it with a different locomotive without the BEMC or RCMC, you'll have to generate the signal it requires. I've never looked at the exact method of driving that part, but it's bound to be pretty simple.
Personally, I just created my own PCB for retrofits, no external signals needed.
I don't see them on your web site?
I don't make a commercial product, I just use them in upgrades. I've posted about them here a number of times. I make a track powered model (left), and a DC powered model (right), the DC one I use with the Super-Chuffer. They're a group of flickering LED's with the tops sanded to diffuse the light. I use a red, orange, and two yellow flickering LED's, makes a very realistic looking fire. That light is filtered through a plain piece of #20 bond paper to further diffuse and blend it.
Ed,
Are you wanting to use that particular fire box flicker? I purchased units from LBR, just two wires to connect, mounted it in my Polar Express. Put the second one in my Flyonel Northern.

Hay John,
What is # 20 bond paper?

Standard copier paper is #20 stock.
500 sheets of 20# 17 inch by 22 inch paper weighs 20 pounds...and that’s a “ream”
Chuck, 500 sheets sized 17" by 22" weigh 20 pounds. 
A ream of standard 8x11 weighs around 5 pounds.
