I have a 2004 Bonneville SE, and I'm looking for a solution to all the 12-VDC power cords for GPS, XM Satellite, Radar Detector, cell phone charger, and other 12VDC equipment that seems to be breeding at night, in my vehicle.

Ordinarily, I would consider cutting the big, clunky cigarette-lighter plugs off each power cable, and hard-wiring them to a 12VDC bus hidden up under the dash. But the GPS plug contains the FM traffic receiver, the XM power cord contains an FM modulator, and so on, the cell-phone charger plug reduces voltage for the phone, and so on. So cutting off the bulky plug-ends would cripple those devices.

So I'm looking to mount a couple 4-way multiple-socket 12VDC adapter gangs under the dash, with the gang-units themselves hard-wired to 12VDC somewhere under the dash, so as to leave the standard dashboard lighter socket free and avoid having to daisy-chain them.

None of the devices I need to plug in, is, itself a high-current device. And collectively, they only total about 6-8 amps when everything is turned on.

Does anyone know if there'* a suitable source for 12VDC power, anywhere under the dash (preferable switched off with the ignition key) from which I can pick up the 12VDC with a fused cable, that can safely handle 10 amps max or so, or will I need to go forward under the hood, or back to the rear-seat for the battery, to get the needed power for the gang-units? I'm thinking of installing a 4-socket unit on each side of the center console.

Thanks for any suggestions.

Check under the drivers side Apiller, there should be a wire there for the sun roof, and that'* switched. Even if you don't have a sun roof, it should still be there.

Dan, that'* a great suggestion. But I've checked the owners manual for the fuse box diagrams, hoping I would see a fuse reserved for the sun roof, so I'd have an idea (based on the size of the fuse) as to how much power the A-pillar wire can safely handle. Unfortunately, I don't see any fuse so designated. Would you happen to know which fuse, in which fuse block, would be the one reserved for a powered sun roof? (You are correct, too, in that my particular Bonneville does NOT have a powered sun-roof installed.)

In addition to the sun-roof, I would expect to also find power in the A-pillar, for the lighted vanity mirrors on the sun-visors, and for the reading lamps in the overhead console. Would you happen to know if those features are part of the "interior lamps" or "front courtesy lamps" circuits, as fused in the rear seat fuse block, and if the sun-roof is part of one of those circuits? I'd like to use a circuit that isn't already sharing a fuse with another function. If the sun roof is it'* own circuit, that would be perfect. If it'* wired as part of the other 12VDC functions found overhead, then I'll consider other options.

Sawgunner would be the right person to ask about this.
