Does anyone have a ground wire diagram for the blacktop sr20det?
And where is the main ECU ground point on the engine?

ecu ground point on the engine???

wat?

google has plenty of wiring pinouts for the blacktop sr20, ground shit where ever, just make sure it has good connection directly to metal, you can't really have TOO many grounds

The ECU ground(s) is incorporated in the common ground that runs through the entire engine harness (multiple ground wires feed into it). The actual grounding point for all of them are the 2 eyelets that are bolted on to the #3 intake runner. Then it completes the circuit to the chassis via the 2 main engine>chassis grounds located off the front of the intake manifold and the rear of the head.

Thank you sir. That was the answer I was looking for. I was just hoping to find an actual diagram or schematic showing all the ground wire connections. Other cars have this.
Thanks again man.
