I too have recently had cobalt gauges installed, and have been puzzling over the dimming problem. In short, it seems Ford has a rather weird way of dimming dash lights. At least I assume all the dash lights dim the same, I've only been focussing on the bulb socket behind the cigarette lighter. Having read the PDF manuals & confirming with a multimeter, the following applies: The lights are not dimmed by varying the positive voltage fed to them, but by raising the earth potential on the negative side using Pulse Width Modulation. This means that when the dash lights are at their dimmest, the "Earth" wire is actually reading +8.45V, with respect to earth. As a result, a normal bulb would be dim, since it has +12V on one side, and +8.45V on the other, hence the bulb only has 3.55V across it, which = dim. When the dash lights are brightest, the "Earth" wire reads +0.265V, creating almost 12V potential difference across the bulb, which = bright. Naturally the other two dimmer settings are in between these - you get the idea. This doesn't help us though, since we only get one wire to feed a positive voltage into the gauges, the other side of which is grounded, as you'd expect. So if you hook up the +12V wire from your cigarette lighter to the gauge illumination input, it doesn't dim at all. If you hook up the "Earth" wire, the gauges dim, but opposite to the dash lights. Bugger. So, I'm in the process of building a simple transistor circuit to get the dimming happening how it should. So far it looks like using 4 components (NPN Transistor + 3 resistors) and costs less than $5 to build, providing you have some wire & solder kicking around somewhere. I should point out that I haven't actually built or tested it yet, that's a job for tomorrow. But it works, in theory. I hope. As for the traction control button illumination, I'm pretty sure I checked it & it was the same as the cig. lighter bulb. However I plan on getting my +12V when-the-lights-are-on supply from there, since the cig lighter bulb does other weird stuff like come on with the interior lights when you unlock, and stays on for a minute or so (or until you lock) after shutting down the engine. Use the cig. lighter bulb wire for cool factor if you like night-lights. Watch this space....
