Headlight short

Just disconnected the headlight switch and sure enough, the wire going to the B-1 terminal was melted + corroded and barely even attached to the connector.
On the other hand, I can't seen to get the switch out to inspect it. I took the knob out, but I can't figure out how it attaches to the dash since the fusebox is in the way.
That fancy chrome piece the knob came outta, - it unscrews.
There's a tool but...... Snap-ring pliers, needle-nose or similar have worked for me.
If it's just the one wire, you can kinda sculpt out the holder, if nec. and use a heavy duty spade. I prefer properly soldered,- but that's a can of worms in itself, lol
Good job . Good luck .
