AEM Infinity

Plug and Play harness installation:

Plug and play wiring harness for Infinity ECUs with the AEM wiring harness:

Locate the 4 pin AEM NET wiring connector on the Infinity harness. Connect the Plug and
play harness into the Infinity harness and run the cable to the desired gauge installation
location. Note that the gauge gets power and the CAN signal from this cable and no other
wiring is necessary.
** Notice** It has come to our attention that some of the first AEM Infinity factory harnesses
had the CAN high and CAN low wires reversed

(Most Infinity 8 Supra harnesses)

. Pin 1

should be White (CAN high) and Pin 2 should be Green (CAN low).
