I am having a really bad time figuring out the freaking holes! I want to purchase a short ram intake for my car, but i can't figure out what 3 of those wire do connected to the factory intake on my Civic 2000 EX.

1.) I want to know how come everytime i remove the oxygen sensor wire and plug it back in the ''Check'' light shows up on my dash board?
-I would have to remove the negative wire on the battery to get rid of the ''Check'' light, i was wondering if there is anything wrong with that.

2.) How would i come about getting a short-ram intake for my Civic 2000 EX?
-Because when i look online to get an intake for my car it has 3 holes for me to plug my wire back into....but the holes are just holes, they do not have the factory plug-outlet holes where i can just plug back in my oxygen sensor and such...

3.) Would i mess up my wires/sensors if i was to remove my factory intake and install an aftermarket one?
-Because i heard that the factory intake has a sensor inside the tube, and i would have to remove that or some crap...

**I DO NOT UNDERSTAND!!! Can someone please help me out...im so confuse!
