My wires were extracted from a Mitsubishi eclipse loom, I think they should be fine.alessandromeyer wrote: ↑Mon Apr 29, 2019 9:04 pm EDIT: by the way the ecu, lambda probe tps and the cranksensor share a common ground post. And speeduino feeds TPS and the cranksensor with 5v. Is there anything i should be concerned about?5V and 12V sensor and signal grounds for Speeduino to read ("sensor return") should all go to one GND terminal or wire on Speeduino. Power grounds (e.g., O2 heater, all of the other Speeduino GND wires, etc) should all go to one engine ground point (star ground). For example, this means your Speeduino power and remaining grounds should be at one location, and your WBO2 controller power ground should be at the same location. A VR- is an exception (VR is alternating voltage and current, not DC), and should be to the designated VR- terminal that feeds the VR signal conditioner directly.
