How do I hook up the nuetral safety switch on a 94 Ford Ranger?

I have a 94 4wd Ford Ranger with a 4.0 Engine, And i put a A4LD Automatic Transmission in it, but I can't get the Neutral Safety Switch or Starter Safety Switch and now I can turn the ignition and it won't crank or even turn over and I heard that was the problem. I can tell where the plug in goes and the wire that goes to it are the same plug in but I just can't get it to go in can anyone tell me how it goes in if there's a trick to it or something?

I really doubt that the harness plug fits the replacement transmission range switch. Even if you get it started it likely isn't going to shift properly.
The trick is to make sure the transmission's are compatible. The PCM is likely not going to work either.
Any auto recycler can look up which transmissions will work in your vehicle.
