ok so i just bought some gauges that replace the clock in my 03 wrx, and the guy said i would need to replace some of the wires and connectors, does anyone have any idea what kinda wires these would be? and for installing i need to use a ground and what else, these are mechanical autometer EGT pyrometer, boost, and oil pressure. where do i put the probe for the EGT, i have a helix downpipe? and what about the oil pressure, because im not sure if they come with instructions since i bought them used? thanks, IS THERE ANY POSSIBILITY FOR ANYONE TO LIST WHICH WIRES CAN BE CONNECTED TOGETHER? AND WHAT EACH ONE IS USED FOR, THERE ARE NO INSTRUCTIONS, OR DOES ANYONE KNOW A WEBSITE THAT TELLS WHAT EACH WIRE IN THE AUTOMETER SERIES IS USED FOR?
