I am now posting on the inliners.org as mogofosho, fyi.  Talk over
there is that the BCM has a serial connection to the PCM and not jsut
a +- voltage.  I have acquired an entire envoy to play with($795, 38k
miles), right down to the key in the ign sw.  Any idea how I could
monitor the line between the BCM and PCM to determine how to get one
of these running without a BCM?  I'm a programmer, but have never done
low level stuff like this.  Since i have the BCM, i'm not as worried
about getting rid of it, but I'd like to help those that don't ahve
one and also get rid of mine someday.  The plan is to do this same
swap to my brother's 65 nova I6 after I get my nova figured out.
