ignition switch in dash

[Stitch]

I need to know how to replace the ignition switch inside the dash that sits on top of the column...I fried it and the connector is a little melted also...I am NOT talking about the ignition switch that the key goes into...I'm talking about the electrical part that's in the dash...I already have the dash apart and the column dropped, but don't see how to remove it...I borrowed a pic from a for sale ad on the forum...I hope the guy doesn't mind I used it...

I also need to know where the fuseable links are at in the truck...I have no power to the truck...no headlights, domelight, nothing at all...thanks guys
