So after getting my ECU i headed down to the garage and well i put the ECU in and changed the transponders over but nothing

the red led flashes its tits off

so i then changed the receiver ring over buts still nothing....
so i changed the engine loom over but now i have to change the dash over as well because of thesse plugs.
so its guna be a pain but i need help with a few of thesse plugs, are thesse all for the rad because im going to put the rad on switch in the car...
Any one got any tips on removing the dash?
