I might be able to assist. My TAF looks like the pic above. I put in lighted purple buttons on my TAF. Used flex LED's to do so. The nice by-product of this it lit up the shooter/plunger area. Maybe cost me $10. Used Comet flex LED's. I ended up tapping power from the coin door (using the wires that provide power to the lights in the coin reject buttons). I can shot some pics on how I did it, if interested.
