Wet Car woes.

[David_Powell@hqlink.cbsi.com (David Powell)]

My 89 100 doesn't like the rain.  Last night it let me sit.  I checked in to a
hotel and waited for it to dry out.  This morning I drove it about an hour and a
half and it died again.  I'd seen this type of trouble before when I eventually
had to replace my car's computer.  Several of the computer's pins were
completely corroded off.  I thought it might be related so I took the dash board
apart and checked out the connection.  I now know how the previous computer came
to be corroded.  I found about 1/4 inch of water laying in the male side of the
plug.  I took the computer completely out and poured out the water.  That seemed
to help.  The car ran for about another mile.  Then it stopped again.  I let it
sit for about half a day and then it brought me home without a problem.

Questions:  
1. The water in the connector seems to have come down the inside of the wiring
harness.  It's not supposed to do that.  How can I stop it?  
2. Since drying out the computer didn't solve my problems completely I have some
other wet places.  What are some of the likely places to look?
3. In general, how do I keep my car from drowning during rain storms?


More information:  While I was waiting for things to start working again I did a
computer diagnostic.  I had error codes for, Throttle body idle switch, Knock
Sensor, Temp sensor, and a few others that I can't remember now.
