[Shotimes] Where do coolant lines pass thru the firewall?

I've done what you're considering.  My 91 had a rusted steel tube, so I
removed the CELO switch and went with rubber hose the whole way from the
engine to the heater core.

Your ETAC will work okay; it will not be confused.  However, on winter
mornings, it will turn the blower on full blast right away.  Normally, CELO
keeps the blower off for a couple of minutes until the engine temp comes up
a bit.

You might be able to get the steel parts from Al Fitz.

I'm just there, now.  Turns out the metal tubes are rusted, as well.  Out of
production; I found one at a Texas dealership.  The other, with the CELO
switch is starting to leak.  Is the CELO switch a necessary part of the
computer input?  If I remove it, will it screw up anything?  The manual is a
little hazy, it may only prevent the blower from coming on while the engine
is still cold.  I'm thinking of replacing the tube with hose.
Anybody know?
