Remove your radio get to get your serial number. Don't worry, it's not that difficult.
http://www.team-integra.net/forum/blogs/morningz/41-g3-head-unit-installation.html If you do not want to go that route, you can go under the steering wheel and peek behind the dash where the radio is held and with a flashlight you can see your serial number...
You'll need it to get your radio code. It should be on it. If you're the original owner go here:
https://radio-navicode.acura.com/?src=inq. If not, call up your local Acura dealership. Ask for Parts department not Service dept. because the the service dept will charge you. After that, ask for radio code because you disconnected your battery. Answer any questions they might ask. It should take less than 5 minutes. Done deal.
For your dipstick, I believe if you take off your black intake hose, look down and you'll see a yellow handle. You'll find it. It's the only yellow thing there. It's on the left side of the motor.
