its worked for the last week and then my mate pulled the clocks around when he fed the boost gauge wire and pipe through. . then it didnt work . ive under the clocks and slide them about and pushed all the connections in but it still wont work?? what should i be looking at behind the clocks and under the bonnet ??

you will have to put it in simple terms cos i aint got a clue about all the bits and pieces under the bonnet. any certain colour wires i should be looking for in or out the car ?
