Keyless entry '97 Civic EX
 

I have two questions for you guys:

My aftermarket deck was recently stolen (broad daylight even, within 20
minutes) from my 1997 Civic EX. I decided to replace it with a factory
deck and an alpine chm-s630 cd changer from eBay.

Question 1: Will I need what I've read here called a ACUALP to get the
Alpine changer to work correctly with my factory deck? I haven't
receive the changer yet, but it comes with Alpine's cable, so I
wouldn't be using the stock Honda one. This is the only thing unclear
in anything I've read.

Once I took the bottom dash apart, I found that the circuit board from
my original was still hooked up (apparently to control the dome light),
but it was missing the front interface and enclosure: it was just the
circuit board wrapped in plastic. I am an engineer and started poking
around the circuit board and noticed the green connector has pins
called unlock, doorlock, light, horn, etc. This leads me to believe I
have keyless entry although I never received a remote when I purchased
the car.

Question 2: Do I have keyless entry? I would rather not purchase a new
remote for upwards of $50 on a risk.

Any help is appreciated.
