hello everyone,

im doing my auto to 5speed swap on my 97 s14, i've pulled out the motor along with the tranny on it and i decided i dont want to use my A/C anymore. i had it but never used it for some reason. i did some searching but couldnt find anything that would answer my question. my question is... do the ports on the firewall where the a/c lines are connected need to be covered or pluged up? since im not going to be using my a/c, i dont need the lines in the engine bay. ..so what do i do? do i need to plug the ports or just leave them as they are? any help greatly appreciated. thanks
