My Ford Transit headlights turn on in off position and turn off in the on position?

I'm a new driver, just passed my test. My van has some issue with the lights: namely, the lights turn off in the on position when the dash lights come on, and turn on when they are supposed to be off. This means that I'm driving at night without dash lights as I need to have the lights switched off in order for my headlights to be on.

Might this be an electrical issue? Would anybody be able to give me advice and possibly know how much this costs to repair?

What does Rule of 10 and Standard Rules of Eligibility apply mean? Cash back question for car finance?

What does this mean? I'm attempting to finance a vehicle and under the finance cash back option, in small letters, it mentions this for the ford vehicle. What does it mean and how do I know if I qualify before going into the dealership?

Also, I have a question about cash back. If I finance I get a loan through a bank or another institution other than the dealership, does that mean that I will not qualify for the cash back finance option offered by the dealer, or is this option only if you finance through the dealer?

Is there a guide to buying transmissions?

So I'm looking at purchasing a new engine, only thing is it comes with an automatic transmission but my truck is a manual, so I need to buy a new transmission. And to accommodate this new engine I would need a transmission rated for higher horsepower anyways. The engine in question is a supercharged 5.4L V8 from a Ford Lightning with about 360HP. What I was wondering, is there a set in stone guide for what transmission to use for what HP, or is it more up to how you want your truck to drive? I would also take any suggestions for transmissions you all have.

Car Ownership History - 10 Digit Vin?

I own an older vehicle, a really old vehicle, and the vin is only 10 digits. Most modern vehicles have 17 digit vins and thus Carfax does not look up vehicles which were made with the previous 10 digit vin or older (before the law changed to 17 digits).

Where is a place I can find the ownership history to, for instance, a 1959 Ford using the 10 digit vin?
