PLEASE HELP! Transmison problems.

In the middle of converting my 2002 prerunner to a 4x4. 6v auto transmison. I have a the transmison out and the new 4x4 installed. It came out of a 98. Was plugging in all the connectors and notice these two plugs are diffrent. What are these for? Im asuming it tells the ecu whether the tranny is in park, neutral, drive, ect. And how can I swap them or some how make this work? I removed the bolt holding it to the trans and the nut and clip. Still not comming off. Almost done and this is one of the last things holding me up.

 

Also I have the old wiring harness

 

Anyone? I gotta get this done today.

 

Spray the heck out of the Neutral safety switch and it will come off

 

Thats the first plug . What other plug you talking about ? the vehicle speed sensor on the rear ? If so , you will need to extend the wiring to make the plug fit on the back of the transfer case now . The Vss is on the transfer case in a 4x4 application

 

It the neutral saftey switch. I've already knew about the speed semsor and extended the wires for it. Didn't wanna pull on it too much and break the neutral saftey sensor.
