Step1: Remove wipers and plastic covers. Drill out the rivets.
Step3: Drill out the rivets.
Step5: Remove plastic cover.
Step2: Remove stock ECU connectors and gently pull out the ECU.
Step6: Install MAP-sensor hose to intake manifold and route it to the MaxxECU and install it. Put back plastic cover.

Step9: Gently bend the ECU plate to make room for the MaxxECU unit.
Step8: Install E-Throttle connector (5) to the E-Throttle module.Use adhesive tape or velcro to install the E-Throttle module up-side down with connectors downwards, to prevent water to get into the module.
NOTE: E-Throttle module is not waterproofed, make sure NO water can enter your MaxxECU products.
Step7: If your vehicle (se table in page one) do have a stock LSU sensor already mounted, MaxxECU uses it directly.
If no factory wideband sensor is mounted, please install a new (in-cluded) Bosch LSU 4.2 sensor in your exhaust system and route the cables to the MaxxECU 16-pin connector using the included lambda cable. See Plugin general manual for wiring information!
Step10: Install MaxxECU CMC connector, MAP-sensor hose and USB cable before sliding in the MaxxECU into position. Use adhe-sive tape or velcro for mounting.
NOTE: MaxxECU V1 is NOT waterproofed, make sure NO water can enter your MaxxECU unit after installation!
Step11: Connect harness adapter to vehicle harness, make sure the connectors are properly installed and secured.

NotesMaxxECU has some built in output test and diagnostics, see Diagnostics ---> Output test to test certain outputs. This will only work if fuel pump is set to ”Always active” since fuel pump relay is also powering injectors and ignition.
