I have an R34 GTT, and i was trying to unplug one of the boost lines so i could plug in the T piece and one of the plugs snapped, its attached to something labled 'turbo gauge' (i think) which goes to electronic plug.
cable is found right near the firewall, center of the car, just behind the factory strut brace.
basically, one of the tubes coming from just before the TB, it goes into a big round circle, red + black, then went into the plug i broke, then to an electronic sensor..which would go back to the ECU somewhere i think...
ill put up pics when i get home, car drives fine... boost gauge still works fine. just wanting to know if i should get it replaced or not to worry.
thanks for any usefull advice in advance
