	That's just it.  We don't have a Chevy computer controlled HEI
handy to compare the wiring.  The Accel ECU comes with the wiring
harness ready to go for a Chevy HEI.  Since the Olds plug is keyed
differently, we were wondering if they had swapped any of the wires around
in the plug.  We are going to try to locate a Chevy HEI this weekend to
compare the wiring of the plug.  If anyone could post a list of what each
of the 4 wires from the weatherpack connecter on the Chevy HEI goes to so 
I can compare it with our Olds HEI plug, I would really appreciate it. 

	Thanks,
