i just installed a new front headlight, engine and main under dash harness. Put the battery back in to test and I'm getting absolutely nothing. Battery shows 12.5 volts. Turn the key and nothing. Purple is on S terminal. I'm getting 12.5 at the starter. I do have the dash cluster out of the car and the instrument plug is not connected. I don't think that has anything to do with it. Seems strange that the headlights won't even come on. Any ideas?
