T5...plugs

okay, i acquired a T5 from my local mustang shoppe and i was wondering about the plugs and switches on it. there is the one in the side of the case which i believe is the back up switch, but there is also one on the top in front. i have no clue what that one would be, does anybody know?

i know it's been asked before, but how much fluid can t5's hold, and what is the easiest place to fill them from? (dextron III right?)

on the passanger side there are two 3/8" pipe plugs... top is to fill, bottom is to drain.

On the driver side there should be a reverse light plug, a neutral saftey switch plug, and then a rounded star-headed screw which you NEVER want to touch because it releases a gear inside the case.

The switch on the front is neutral safety switch.

Dexron/MerconIII

takes 3 quarts.

I found it easiest to just dump the three quarts in through the shifter hole. Of course my console and everything was off at the time, but that shouldnt be much trouble, then the 4 bolts that hold the shifter on.
