2.Disconnect battery from vehicle.
3.Remove and disconnect stock ECU from vehicle harness.
4.Install MaxxECU adapter harness.
5.Route the included MaxxECU MAP-sensor hose to the intake manifold and connect into the MaxxECU.
6.Route wide band lambda cables to exhaust system, install lambda sensor in exhaust and wire the lambda sensor as instructed below if your vehicle not have a stock LSU sensor(s) mounted from factory (see vehicle cover list on the top if this page).
Note: MaxxECU RACE plugin ECU kit, might not fit into the standard plastic ECU box. Make sure to mount the ECU away from heat or water!
