I'm trying to the VTM wire from my V-acf to the blue plug of the ECU but what's the tool called I need to do this? I know some guys that's used a screwdriver to do this, I had tried this but the wire keeps popping out, checking the other pins there seems to be a metal tab that's missing or is that the wire sticking through the plug?

Does the white and blue parts come apart so you can wire it?
