Thanks for the replies everyone. I'll try and trace it back and see where it comes from. Could it be anything related to the dash, such as the clock or even the tacho? Reason i ask is that ever since discovering this wire, the clock resets itself to 1:00 every time i start the car. The tacho also doesn't function anymore... One more thing, although the car is a GTS-T, it's been transplanted with an 25DE engine. Hopefully this extra info comes in handy to someone
