Right, i have the standard temp gauge in the dash and a aftermarket gauge in the centre vent, i stupidly thought id T into the standard temp gauge wire for the aftermarket gauge but all this did was kill the supply to the standard gauge, so the other option i have is to fit another seperate temp sensor in the block or head but the problem is where?? do any of the b18ft gurus know of any blanking bolts i can use to put the sensor in?? thanks in advance
