If you're using GM sensors, you need GM pig tails(the harness end that plugs into the sensor). O'Rielly's can get them for you. You wire them in according to the directions with the ems.
AEM manual has the pins you use for both the ait and the map. it is also on there website. You will also have to run a sensor ground wire to the ems as well. I chose to use aem brand sensors.
