Gtr_lee Posted September 22, 2023 Report Share Posted September 22, 2023 Hi, i have a g4x with 2 of the 4 pin can ports and i am wiring in an aem x-series inline wideband via can. i have already wired in the can H, can L & 12v to can 2 via a Deutsch plug with a 120ohm resistor. Can i wire the ground from the Aem controller to the can port too or is it better to ground it to the body/engine? was unsure on what type of ground the can port is thanks Quote Link to comment Share on other sites More sharing options...

Adamw Posted September 22, 2023 Report Share Posted September 22, 2023 The NB2 has the 4pin CAN connector which is designed for powering CAN devices up to 3A. You can connect the AEM direct to 12V and gnd in the CAN socket. Quote Link to comment Share on other sites More sharing options...
