I accidentally pulled the wires off the neutral safety switch and am unsure on how to rewire it. Can you please provide me with the wiring diagram for the neutral position sensor for a 2004 Lexus GX470 with a A750f transmission.

Finding the connector views is rather confusing, but I think this is the right one in the third drawing. Let me know if this looks right.

I see that. I think the site owners are in the process of updating something to allow different formats to be uploaded. I'm going to try again and see if other formats work.

Rats. I tried the four other formats on my computer. One wouldn't upload. Looks like the other three don't work either. We'll have to wait until this gets sorted out.

In the meantime, I'll do the best I can with a description. Looking at the connector from the terminal end, with the wires in back, and the locking tab on top, there's a row of five terminals on top, numbered 1 through five, left to right. Under them is a row of tour terminals numbered 6 through 9, again, left to right. Terminals 6 and 9 are much wider than the others.

From the diagram, the wire colors correspond to the following list of terminals:

1. Green / black
2. Red / black
3. Green
4. Blue
5. Green / white
6.
7. Green
8. Green / red
9.

No wires on terminals 6 and 9. Two of the wires are shown as green, and on my diagram, they don't list the gauge, or diameter, so to figure out which one goes to which terminal, the green wire for terminal 3 comes from a fuse that gets 12 volts when the ignition switch is on. The other green wire goes to a joint connector, then turns into two other wires. I can't tell what voltage that one will have, but that green wire coming from the neutral safety switch gets the 12 volts from terminal 3 switched onto it when the transmission is shifted to "drive". That tells us at other times there will not be 12 volts on it.

(Turn the ignition switch to "run", then the green wire with 12 volts on it goes to terminal 3. The other green wire should have 0 volts, or at least something other than 12 volts. That one goes to terminal 7).
