I am trouble shooting a fuel gauge problem and I need to check the ground for the rear license plate light. It is the same as the taillight ground it is G511 on the electrical diagram. Where is it located on my 1990 Civic SI? I would prefer not to remove any more than necessary to get to it so I thought I would ask instead if guessing.

 

G511 is located behind the plastic panel, below the latch switch.

 

Thanks, do you just know that or is that documented in the service manual somewhere that I didn't find it? I would like to know for future reference.

 

I have access to Honda electrical troubleshooting manuals which includes photos. They are different than the service manual.
