7747 A/C enable

[Brent Obermiller]

Thank Steve,
I'll keep r-409 in mind, but it's charged, working, and this is the 2nd 
conversion I've done.  Apparently, I was fortunate to wire the first one 
from scratch (as the A/c was partially removed).  I'm at work and don't have 
the schematic diagram in front of me.  I have to 'fess up and say I wasn't 
around when it popped, I only found the puddle of oil under the car and 
coating on the valve covers.  Perhaps it got to cold and broke the solder 
joint and then leaked after it warmed up?

I think...

ign

A/C sw.

Low Pressure Sw.(N/O)
|
High Pressure Safety Sw. (N/C)
|
Relay Solenoid
|
ECM transistor (floats for A/C on)

*part Two*

ign
  |
A/C Switch
  |
Relay Contact (N/C)
  |
Clutch Sol & Diode
  |
GND


Also I'm not using the Bosch relay.  I'm using an '88 Monte 4.3l fuel pump 
relay for both the A/C and Fuel Pump.  I'm not using the oil Pressure 
override for the fuel pump, and so the a/c relay makes a nifty spare... in a 
pinch. ;-)
