I know it wasn't you who said it. Sorry if you misunderstood. I just wanted to be clear for the rest of the people.

Correct.

Nissan moves the reverse light switch wires around depending on year and transmission. You can't always assume that they're in the same place. It's best to find the plug on the shell and hardwire that to the lower harness.

Nissan also moves the VSS wiring around. Most likely the VSS is not even plugged into the right plug.

You can't match the lower harness by plug. You have to match by wire. Figure out what each wire does on the body and lower harness. Mate them together however you want.

If you try to match by plugs then it may plug in but most likely it won't work. Plus you'll have a few plugs that have no mate.
