I don't suppose there is a similar fuse that could be done to for the supercharger? All I want is an indicator, I don't need the extra switching you're doing.
On the fuse #13 right and since an LED does not draw hardly any current you could use a very small gauge wire, strip about a 1/2" of insulation off, pull the fuse, put the wire directly under the fuse blade and put the fuse back in. Either side of the fuse will work, but it would be best on the side that goes out to the pump. If I remember correctly it's the one toward the middle, but if you have a meter pull fuse #14, turn the key to the on position and see witch side of where the fuse plugs in has 12 volts. You could do the same with #13, but you would need to get your pump control module to turn on first then put the wire on the side with no power. As far as the supercharger goes I've not confirmed that the two wires going to the clutch are + & -, looking at the drawing in the tech manual the clutch appears to be in series with another component. I've not found a fuse just for the supercharger yet, but I have not had the time to look hard for one.
