AEM’s Plug & Play CAN bus Communication Harness (PN 30-2213) eliminates the need to manually wire a CD-5 Carbon or CD-7 Digital Dash Display to the MSD Atomic TBI EFI system! This harness is fully terminated and connects the CAN2 input on the CD Dash main harness to the CAN output on the MSD Atomic TBI harness. Additional power cables are not necessary as the CAN connection from the MSD Atomic TBI will power the CD-5 Carbon or CD-7 Digital Dash Display via a “Y” connection to the AEMnet port for Power and Ground
