Today I sorted out the wiring and = everything=20 is now working.  The only problem is that the manifold vacuum = gauge=20 is reading backwards.  I tried changing the plus-minus wires = around=20 on the back of the gauge and it reads nothing, even with vacuum=20 applied.  The question is what happens if I switch the power = and=20 ground wires around, does that do anything besides blow the fuse = or the=20 gauge.  Will run the engine again tomorrow with the ole steam = gauge=20 and try and get a start on the EC2 tuning.
