420A Engine install, where do these plug into?

Hi!

Just about about to wrap up an engine install but I cant for the life of me find where these lines/plugs go. Any help would be tremendously appreciated.

The connector in the first pic goes to the reverse switch on the top of your transmission (kinda under the battery tray). The second and third pics I don't know ( sorry). The last one I believe goes to your intake to firewall (grounding point). Sorry I didn't have all the answers, but hope it helps.

Okay. I went back out and checked, and If I am looking at the right sensor on the trans, its towards the front. However, I already have one plugged in there. The unknown connector has 2, close together round pin holes, and the sensor on the trans has 2 farther apart flat pins. As for pic 4, so, it connects just to the manifold itself? And then grounds to the firewall?

The grounding cable goes from the firewall to the intake manifold. I have mine connected to that flat piece that let's you adjust the tension on the throttle cable. The other end goes to a point on the firewall (chassis ground). I am not home, but if you still need help by then, I will look at my car and let you know. Do you have access to the tech manual? I think I might have seen some info in there that could help you.

Alright, for future reference, if anyone ever needs it, the first pic is of the red trimmed plug goes to the EGR, 2nd plug isnt used, the 3rd pic is a vacuum line that bolts to the frame and routes up passed the cam gears(per a loaner car i looked at), and barza was spot on about the ground wire.
