One more thing, I am attaching a picture, the terminal that says "ground" this would normally go to the safety neutral switch. This box should be located near the battery. Find this box, see if there is a wire connected to the "ground" terminal, if there is disconnect it and run a jumper wire from this terminal to a good clean ground (be careful as the main battery stud is just above it and will spark up and scare the crap out of you, disconnect the battery while you do this). Then, once grounded try the key and see if anything changes. Also, note that in your car this box (relay) could be mounted upside down, so look carefully at the lay out.
Did you put the push button switch in? If so, how did you wire it?
