I seem to have all connections made to the body harness and all electrics seem to work in the back:

- passenger door switch

- room lamp

- all tail lights/turn/rev/4way flashers (except brake light which I will chase down today)

- license lamp

- marker lights

- speaker

- power antenna

- defrost

- fuel sender

So I am wondering what the 3 unused wires in the body harness do?

One is red and seems to be a loner with a long-ago broken off connector

The other two (which seem to be paired) have the bullet connectors (one is black and the other is red or red with a black stripe..I forget exactly).

The only two single wire connectors that I connected to the body harness were a green (bullet) and also the one from the pass. door switch (blade).

Philip, where are these wires relative to the body of the car?

Thanks Steve,

It is a 71 240z. They are at the head of the harness that goes to the back of the car. This location is in the passenger kick panel area near the top door hinge.

Here is all the FSM shows (I added the red and the black and red paired):

Black and Red/Black paired wires are the pair that feed the Rear Window De-Fog circuit.

I re-checked. One is red with blue stripe and the other is black.

Philip, look at the upper right hand of the wiring diagram from the supplement. I'm not sure what Step L really is, but it has that wire color combo.

Step L is for the step light on the right side. Do the wires look like the blue taped ones in the photo

I think that matches up to what Philip posted.

Yup that is it

Thanks!

What about the solo red wire? I thought it was a PO addition but I dug into the harness and it was dressed in at the factory.

Is there any chance you can trace out where the other end of the mystery wire goes to? Did the 71 ever have a speaker in the back?

I went out and looked at my car and can not find a red wire in the body harness.

Thanks. I'll take a photo today.

The harness is now in the car and difficult to trace.
