ignition wiring(HELP)
 

I took out the dash on my 83 ZX 2+2 and I disconnected the dash harness from the main harness and I also took out the wires from the taillight, fuel pump, everything. Once I put the dash back in and wired everything up the car didn't start. The headlights and lights work for the dash but the gauges and accessory lights on the dash, don't turn on at all. It's like when I turn the key, nothing happens not even the fuel pump turns on and the fuel pump wire and fuel pump wire relay are plugged in.The battery volts on the dash gauge works but that's it. I looked at the ignition switch and the red/blue wire is cut. I read somewhere that the wire connects to the dash harness but idk where. Please help me figure out where the red/blue wire connects to. This is my theory on why the car wont turn on, It is probably not but I can only hope. the car ran fine before I took out the dash and now it doesn't even crank, it did have problems with idling and it would struggle to turn on but it did crank(this was before I took out the dash) I need to clear the fuel lines and cant with fuel in the lines.
