Just a quick question. I am wiring up my sensors and eids stuff and started wondering, should I try and ground everything in the engine bay, or run all the ground wires with the rest of the wires and ground them in the cabin? I can't imaging it matters much, but figured I would ask before.

i always ground the sensors to the ms and my ms and related stuff to the battery and im not having a single problem with noise in any signal.

K. I was asking cause I bought the diy auto tune relay board. The ms connects to that and all the sensors, injectors connect there, but I dont recall seeing a place to run all the grounds for the sensors. Maybe I need to look up more on it.

The sensors ground to the return terminals on the relay board.

Thanks. I should have looked at it closer before posting.
