First Ill start off with the gauges. Im going with Autometer boost and EGT Gauges and the AEM wideband. What besides the gauges to I need to buy in order to install the gauges and to get them to work? Any wires or sensors? Also I am going with the Greddy Emanage Ultimate and want to know if I need the PnP harness that is $350 or if I can go with the universal harness that is only $90. Thats it for now but I will update with more questions as they come come up. Thanks for the help.
