dash wont work and wont start
 

hello,
I went crazy and cut most of the wires off the ecu harness because I am running a stand alone.
Now, the car won't start, dash lights and gauges don't work. The turn signals, headlights, and wipers do work. I have not hooked up the hvac controls yet so I don't know if they work.

Does the ecu control the starter, dash, and hvac? THanks for your help.
