stick the multimeter on the battery and tell us what it reads.

11.53 V from the battery,The wiring to the ICM is little different on the 96-97 models, so the colors don't match up right, but i figured it out. aroud 12V from pink wire (to ignition) on the harness going into the coil, and about 12V from the outer wires (to coil, i think) on the harness going into the ICM. I cranked it and check the other lead, It was jumping alot, but it was from 0 to 1.4, not 1-4 like shbox said it should be. And there is definitely a bad ground or short somewhere, the clicking/flickering has gotten worse. I couldn't even turn the key it just kept doing it and eventually it stopped, the seatbelt light a few other lights flash along with the lights as it clicks away. For this reason i think im gonna take it to the dealer, if it were just the opti (i prob need this too), it would def not being doing all that nonsense.

yeah without seeing this in person, its tough to diagnose. especially over the internet. i would just retrace and recheck everything you did. if there wasn't a problem with the interior lights and such before, it should be something you did.
