PLX Wideband to KPro V4 Install - Correct Diagram?
Hey all,
I know this question has been answered a few times, but I'm still not 100% confident I'm wiring my PLX wideband to my Kpro V4 correctly. Does the attached diagram accurately depict the correct setup? (NOTE that i'm not using the TX connection method as depicted in this diagram from the S2000 board which is making me second guess myself https://www.s2ki.com/forums/s2000-force ... 4-1195893/)
Thanks!

DO NOT ground the PLX box to the ground on either the digital or analog plugs found on the S300 board... you will destroy it. Ground that wire to either the ECU ground wire or the engine harness main ground at the thermostat housing.

If I've still got it wrong, my question is then: Where do i ground the analog ground wire coming off the kpro board?

Thanks for the feedback! I think my diagram was inadequate. I don't (think) I'm grounding the PLX box to the kpro board. I updated the diagram with where I intend on grounding the box (see stared items).

You don't have to ground it all the way out on the thermostat housing. Attaching to IGP and PG at your ecu connectors will get you on the same power/ground plane as your ecu so you don't have any offsets.
As mentioned above, never use the kpro inputs for power circuits or you will be buying a new one. They are only for signal levels (5V very low amperage).
