[s-cars] Ignition Switch woes....and lessons learned

Ok, I'm trying hard not to smirk here.  I doubt there is any default   
to starter on in them books, Craig.  You probably just had a  
difficult time seeing exactly
where every connector was with your big mitt in the hole also.  :-)   
Not exactly a lot of working room in there.

In that same area, I had to change out the stalk switches because the  
headlight high beam switch failed.  Not wanting to tempt fate and  
having to disconnect the airbag,  I did follow the Bentley and  
disconnect power.  But when I pulled the plug off the wiper  
connectors, the wires pulled out of
the plug,  all seven to wipers and washers.  How lovely, I thought.   
I had a good feeling about 5 wires but no clue for the other two.   
So, punt, then
power up to check.  All is well on power up except the washers squirt  
with the right turn signal and the washer turns on the turn signal.  
The obvious
swap fixed all.  But what a moment when I looked at all those wires  
loose in my hand.  Beware if you work on these, the connector pins  
are just
round pins and do not have the double barb holding them in the  
connector like the Amp connectors in use so many places on the car.
