Push Start System?

Hi,

I have a few questions about installing a push start system.
1. Can I turn the car on with the remote start? It's a manual, but I heard if you leave it in neutral, it will start. But I'm sure that's for newer cars since my car vehicle above is a 2005.
2. Will it require me splicing my kit with the OBD2 Reader?
3. It says it has oil pump detection, what does that mean?
4. It also says it has a feature where it will turn on the A/C, but my A/C system uses knobs to turn the blower on, and a button to turn on the A/C. Will it work? (First image for reference)
5. What does central automation lock mean?

I know these are a lot of questions, but please bare with me. Thank you.
