AEM offers two sizes of wiring harness for easily installing an EMS-4 onto your racecar or Powersports racing vehicle; an 18" flying lead harness (PN 30-2905-18) and 96" flying lead harness (PN 30-2905-96). Both wiring harnesses have weatherproof connectors and color-coded, silk-screened and bundled wires to ease installation, and are pre-wired for AEMnet, power/ground, CAN and remote USB. The connector, plug, USB and wire seals are weather resistant.

Users who want to create a custom harness can use AEM's EMS-4 Plug & Pin Kit (PN 30-2905-0). This kit is ideal for creating a custom harness that does not require hard wired analog, analog/frequency or to switched-to-ground digital inputs. The EMS-4 Plug & Pin Kit is pre-wired for AEMnet, power/ground, USB and CAN leads, and includes a bag of 20 terminal connectors for populating your inputs.
