Oh man, are you in luck!

You don't need any of that. It's real simple.

1) Run a hot wire from a power source under the dash. Or, just run one directly from the battery.
2) Pick a ground....any ground from under the dash and run a wire....
3) Run both of those to a splitter or splice so that you then have two of each to hook to a double pole/double throw rocker switch mounted at a select location on your dash or console.
a) On the switch, you will have two poles on each side and two in the
middle.
b) Take one power and one ground, hook them one end, swap the other power and ground and hook them to the other end. The two terminals in the middle of the switch are the sending wires that you run to the window motor. Like this:

+ -
s s
- +

As you can see, the polarities are switched so that when the rocker is pressed one way the window goes up and the other the window goes down.

4) The sending wires can go to either side of the connector of the motor, if I remember correctly. If it doesn't work that way, you'll know and therefore just swap them around.

Make sense?

Note: This method "hot wires" the window directly to the battery. It's safe and I've had my '86 4rnr working like this for years. The only draw backs...if you believe them to be....is that there are no safety features as would be with the factory set up (the window will operate whether the gate is up or down) and you'd therefore have to be a lot more careful. Also, there is no provision in this for operating defrost or the rear wiper, if those are important to you. Nevertheless, the window will work.

thank you for the help i would acualy like the rear window and wiper to work properly but i will take your idea into concideration if i cand get the factory way to work

Well, for the wiper, you'll need the relay board that goes in the body cavity behind the driver's seat. Do you have that?

I'm pretty sure I've got one laying around in the garage. LMK if you need it.
