i just recently dropped an b16 in my car and the motor came with the ac pump. how hard is it to install ac and what stuff do i need to buy. all i have is the pump. also wondering if there are any major wiring do i need to under the dash.

 

the dx didn't come with any ac or anything at all?

 

oops hit enter to fast...if it didn't come with ac your gonna need the under dash harness(unless it's already under there)...the buttons(which i have and could possibly sell you if you have paypal)...and to mount the a/c your gonna need to get the a/c mount off a civic si(basically get all the a/c stuff from a civic si)
