non turbo to Turbo ECU swap

[Phalanx99]

My car is 97 Spyder GS. I just swapped in the EPROM 95 turbo ECU but I couldn't start my car. The problem is I can't get sufficient power to my 95 turbo ECU. From the installation guilde, I should feed a 12V wire to pin 82. Someone told me that I can get power from one wire of the Fuel Pump Module but I don't know which wire that is. The fuel pump module has these wires:

pin 1: black/red wire
pin 2: white/red wire
pin 3: black/blue wire
pin 4: black/white wire
pin 5: black wire

So which wire should I tap the positive wire to feed my ECU ?

Thank you

The black with white stripe should be the wire from the IG1 terminal of the ignition switch. The FSM says both pin 3 and 4 on the 2.4L Spyders are the same signal but you say you have a black with blue wire so use the black with white but make sure that it's the one that has 12v in run and start on the ignition but not accessory.

Ok this is all what I did to the ECU swap:
- Signal wire from Knock Sensor to pin 78
- Power wire tapped from pin 4 (black/white wire) of Fuel Pump Relay to pin 82
- Pin 1 and 3 of Fuel Pump Module are soldered together
- Pin 2 of Fuel Pump Module is connected to pin 2 of Fuel Pump Relay. The wire from harness side of fuel pump relay left unuse.
- Pin 4 (black/white) of Fuel Pump Module is grounded. The CONNECTOR side left unuse. I did this because I couldn't finish the fuel pump rewire.

I still CANNOT start the car. Any idea ?

I did swap the plug 1 to 2 and 3 to 4 because the firing order is different from 95 and 97. Again, CANNOT start the car (
