i did not get the ABS light to blink or anything. It just stayed lit up! I am fairly confident I put the wire in 5 and 15 and turned the key on. why would it not start the diagnostic mode? thanks rich

Here is how it should look. Disregard the 'service engine' light flashing on the left side of the cluster.
