Yeah i am getting so many errors its crazy. I only get questionable data every like 20 seconds. On the plus side i know we were trying to work through the whole error deal with the harness being close to the plug wires and all but i am going to buy a new harness pre made, YAY, although it wont be installed for a couple months.
Any thoughts on my next move? Thanks for all your help so far.
the 7747 is known to have issues causing a 51 code to be set. I have seen some advice on thirdgen and fullsize chevy about using the moates socketbooster to correct that problem. I just replaced my ECM when I had that issue and solved the problem. Also be aware that your miss could be a worn distributor.

I looked over everything and saw nothing out of the ordinary. I checked ground with my dvom from the battery to the engine and body and everything read the same voltage as if i was touching the two posts on the battery.
Have you driven it since the night you found your headlights not working? If you can drive it and datalog, even though you are getting errors, it may show something. It is hard to diagnose with such little information to go on. If I remember correctly, did you install a zif socket into the ecm?
Yes i did install just the modified zif.
