OK Guys,

Now we're cookin with gas......

Still need location of Item #80, Control Unit (referring to schematic from above).....

Still need any electrical info available on control unit.....i.e. what is the "at rest" (ignition off) condition of the outputs to any ot all of the devices that it controls......

What are the input signals, and where do they come from???

Pin or terminal diagram.....

Schematic.......now that will be a big time plus......then we couls get them tested at our local electronics/computer geek's shop......

Keep the ideas and facts coming....

SB
