Hi guy's im building G type 2001 1.8 based  im at the dreaded wiring stage and i seem to have lost one of the natural switch wire's from G,box i have a purple with silver rings.

Hi, I think we need more info before we can be sure what the issue is here.

I'm guessing you mean neutral switch - purple wire to the ECU (PCM), the other side of the switch should be a black ground wire.
