Hi KaiH,
the "ground to bridge" wire is a wire that links the ground wires at the back of the pots to the bottom of the bridge (therefore grounding the bridge and strings). There should be a drilled hole under where the bridge will go. Feed a wire from the back of a pot to the top of the drilled hole. Have the wire strands splayed out a bit and literally screw the bridge down onto the wire strands. If the bridge is a black bridge it will need some of the (non-conducting) paint scratched off (or sanded off) to make a good contact with the metal of the bridge.
As for the pickups not working - can you please post a photo of your circuit wiring and soldering - hopefully we can determine what is wrong from that.
+1, a few pics may help. Also the should be a pretty interesting kit.would love to see what you've done with it ;-)
Can we assume you are using the PB wiring diagram for the IB-6s?
If so you may want to keep a couple of things in mind.
About the grounds (earths)...
You need to ground the bridge as TD says. If there is no hole pre-drilled you will need to add one. You'll need a long drill bit. The hole can go either to the bridge pickup cavity or to the control cavity, whichever is closer. You may also need to scratch off the black paint where the string makes contact with the saddle or (preferably) where the string ball goes in the hole at the back of the bridge. You ground the bridge mostly in order to ground the string, so there needs to be continuity from the wire, through the bridge to the string.
Ignore what the wiring diagram says about the purple wires. They are essential ground wires. What is a little confusing in the diagram is that bothbthe gray and the purple wires are ground wires and need to be connected as shown. This is also true of the bent lug on the volume pots. Make sure they are soldered to the pot housing. All pots should have a ground wire.
You can test the grounds with an ohm meter (most multimeters include a setting for ohms). Clip one lead from the meter to ground (aka shaft) on the jack. Tap with the other lead on everything that should be grounded working backwards from the jack.
A disconnected ground might be a cause of "no sound". There are other possible causes, but that's the first one I usually check.
If that's not it the next thing to check are the hot leads, working backwards from the jack. That's more of an eyeball thing, and not quite as straightforward to check with a multimeter as the grounds.
If any of this works let us know, or send pics or both ;-)
