Without wiring diagrams, it would be next to impossible for you to trouble this! From the way it sounds - you caused a short, which of course blew the fuse, and that short could have messed up all sorts of things. Very possible the 'puter!
As for the ABS light blinking, you may have also damaged the ABS control 'puter as well, but most likely it is the ECU. ABS just is not getting the proper signal from the ECU with then causes the ABS light to flash signaling a problem in that circuit.
I have search for a while and cannot find a list of codes for the ABS anywhere!! AAGGHH!
