Finally got around to mounting and hooking up the Flux Capacitor. With the help of the GI Buddy by Dk Pinball.
This version of the Flux Capacitor is the usb charger from ThinkGeek.com. I first removed the cigarette adpater from the back which basically is just nutted on and clipped the 2 12v leads. These leads were then ran up to the power board where I also installed the Data East Power Tap also from DK Pinball.
Now since the Flux has to be powered on each time I solder those leads closed and ran leads from the pop bumper below the ramp to the GI buddy. This way the Flux Capacitor only lights and activates with the pop bumpers and pretty pleased with the results.
