So I probably just wasted my money purchasing the password jdm wire harness for my oem jdm hid headlights as it doesn't include the 5th wire for HIDs. My headlights already came with the harness plug with plenty of pigtails. But... I already started to wire everything up with the password harness and I need to add the 5th wire to it now. I want to take the gold spade out of the existing oem plug that I have. I removed the white center core to the plug and I've tried everything to get the wire out. I can't seem to crack the code on this thing. Has anyone removed a wire from an existing harness? Please let me know what the heck to do....
