Being that the first car shows are just around the corner it looks like I am going to have to close up the '34 before I can get everything fully implemented.  One is the audio interface.  Plan to break into the stereo system between the controller and the power amps.  Probably will just use relays to redirect the four channels into he one audio channel from the ECM.  To this end I selected one of the spare general purpose latches (DATA17) and and connected it to the rear panel 37 pin connector (J300-15).  Need to jumper E9 t E17 to accomplish this.
