Car is 99 gsx. Long story short the wiring that leads to my ecu plugs have been hacked up horribly bad from various owners and past piggy back/gauge wiring. I've owned the car for years and have finally got around to cleaning things up. I discovered my wideband data logging ground had been wired into a random black wire that did not lead to the ecu. I have owned several dsm and always wire mine to pin 92 sensor ground. That leads me to wonder where this wire came from as its not been cut off from the ecu plugs. I found a cut black wire that is connected to the shielded wires that are contained in the green sleeved wiring harness. I suspect this is where that wire was cut from. Anyone know about the cut wire I have pressed against my middle finger in the pic? It is connected to two shielded wires. Does it go to pin 92 or back into the harness? Also, the shielding for my knock sensor is not connected to anything I suspect it was once crimped into the bundle of wires that go to pin 92 correct?

Those look like they should all go to chassis ground to me.

thats all factory actually. you most likely found it wrapped in grey colored electrical tape. supposed to be like that. just wrap it back up good.

Thanks guys I know it was done factory with all the wires crimped together the only wire I'm concerned with is the one I'm touching with my middle finger it is cut and I need to know if it goes to pin 92 or out into the harness to a chassis ground somewhere.

Sorry to high jack, can anyone tell me which specific chassis ground those go to? I'm having issues with my car blowing the sensor ground and I'm wondering if this is my issues on the engine bay side.

the wire touching your middle finger appears to be factory crimped to the bare unshielded lines just as it should be......I dont see anything that was cut

The piece of black wire touching my middle finger is only about an inch of wire the rest is cut off. Maybe this is clearer?

Any luck figuring out where it goes?
