yeah checking for continuty.

yeah sorry for sorry ass pics. Best i could do.

The thing is, if a test requires a harness to be connected.. theres no way to look directly into the plug and stick the lead into the metal terminals because basically its already plugged in and engine is on. So that's where backprobing comes in. But the Nissan FSM seem to use that harness image for the disconnected and connected harness, so its confusing as to whether to look directly into the plug or probe it from the back where the wires are going into the harness (when testing for ground and engine is off).

Thanks for the reply guys this is really helpful.
