How to wire a neutral safety switch for 96 voyager?
Unless you broke into more wiring than you should have, the tach & fuel gauge should have nothing whatever to do with the neutral safety switch.
Shortly, the neutral safety switch requires only two contacts that should "make" connection when the vehicle is either in Park or in Neutral, but no other time. That connection should energize a relay under the hood that makes it possible for your key to energize the starter solenoid and crank the engine. It (the neutral safety switch) MAY additionally have anything from one to a dozen other connections - to indicate the shifter position, for example.
Some vehicles use two switches, discrete from each other, to function as a neutral safety switch and a shifter position ("PRNDL", pronounced "prindle") switch. Yours apparently has a PRNDL switch separate from your neutral safety switch... so the third contact is somewhat of a mystery to me.
Try to return everything under there to as close to original as possible, and we'll start over with this. If you cut any wires, splice them back together. If you spliced any wires, take them back apart.
To fulfill its purpose, a neutral safety switch needs to have some power coming TO it and some power coming back OUT of it. It acts as a valve for that power - P or N open the valve, all other positions close the valve. So... you need to determine which two contacts are CONNECTED when the shifter is in P or N but are not connected any other time. You'll want a meter, I'm pretty sure. to find those two switch contacts. Identify them, make a note on a slip of paper, take a photo with your phone or camera, whatever. Remember those two.
Now find the connector that used to connect to the old switch. One of its contacts will have some amount of electricity (probably 12V or near to 12V) on it WHEN THE KEYSWITCH IS TURNED TO START. Have an assistant sit there holding the key in the start position while you check for voltage. Voltage should NOT be present on that wire when the keyswitch is NOT in the start position. Remember that wire by color. Write it down on your slip of paper, take a photo, remember it.
You have only one wire left to identify - thats the one that your neutral safety switch uses to energize the relay under the hood, and it's easiest identified by making a quick temporary jumper from the START wire (which you just identified) to each of the other two contacts in the same connector WHILE your helper holds the key in the START position. Transmission really in P, of course, so your helper doesn't inadvertently start the vehicle and turn you into squished sausage. So... just touch your jumper from the START wire to each of the other two wires, one at a time. One of them will trigger the starter motor and the vehicle will try to start. Remember which wire that was - by color, photo, whatever.
Now you have your two valuable wires and you know which are your two valuable connections on the switch. Connect your two valuable wires to the two valuable connections and be happy. Please make the best possible connections by the best means you can muster. You won't want to do this again, at 11:30PM on a Sunday night, in a November rainstorm, in a mud puddle, with lightening crashing around near you, while the zombies slowly creep nearer and nearer to your hiding place. You can see them, you can hear them, and you really need to get away from them NOW. You want it to start NOW. Make that a good splice.
