Rained-in Wrangler with Electrical Short in Steering Column

[BLC News Account]

HELP. 2000 Wrangler Sport 4.0L. Top was off, rain got in. Lights/highbeams stay on, drain battery, smoke rises from steering column, battery disconnected. Seems like short in turn/high beam switch. Advice anyone on repair, where to get a new switch, and/or electrical/steering column schematic/diagram for replacing/troubleshooting?
