Few Trans questions

[Zufelt]

What's up guys!! Almost done with my swap to auto thanks to this forum, you guys have been a big help, and a huge information database. Unfortunately I have a few questions that I can't seem to find. The Auto assembly has 3 wires, one for the gear selector, and the other two are for what? I am NOT using a tcu so I can't image what they would go to other than perhaps to lock the assembly in place. My other question, while it may sound silly is I am missing my intermidiate shaft on the driver side.. it's being shipped and will arrive Monday. I checked the fluid level (in the trans) , and it seems to be where it it is suppose to be. (It leaked a lot out, since I didn't have the shaft in. Anyways, to my question. If I lift the car up on all four, can I start the car, putting it into all gears to make sure everything goes smoothly? I'm a little impatient and would love to make sure it's all good as soon as possible. I'm just worried about messing up a gear due to one axle being in the trans, and the other off. Any info would be greatly appreciated! Thanks again fellers

Well today is monday, so I get the rest of my parts, but I still do have one question. I'm not sure where the other two shifting wires go to, and how important they are. I have the one for the trans hooked on but not the other two.. if it makes a difference I'm NOT using TCU
