I had to hotwire my truck last week last week 'cuz my ignition switch started smoking where all the wires go into it, so I cut the wires from the back and put the red and yellow together to get the truck started, now today after work I put the wires together and it won't start

I got power to the red wire, but not the yellow one, I'm afraid it may have a cut or worse melted somewhere, where does this yellow wire go to? anybody has a diagram for the ignition switch so I can re-wire eveything until I get another ignition switch? my truck is sitting at my work's parking lot, and another thing my turn signals don't work anymore.
TIA.
