clip0229

7. Connect the MaxxECU adapter harness in vehicle harness adapter and place the MaxxECU PRO unit above.

Don't forget to mount the included Bluetooth antenna (1), MAP-sensor hose (2) from intake and the USB cable (3) before

assembling rear seat.

 

Note: Preferable route the included MAP-sensor hose right next to stock engine harness and find a suitable vaccum/pressure line

available on your application (on our test vehicle we needed to remove E-Throttle body to find a good MAP point).
