Black and White Plugs behind TB and MAP Question

[HoodStrype]

Hey guys, my friend found a couple of plugs (something for fuel) behind the throttle body... two plugs, one black, one white. They look like part of the wiring harness. He has the same two on his, but on my car it had some kind of wierd extensions!?!? We can't figure this out- there was an extension about 6" long on each wire and they matched the plugs perfectly.

Anyway, I wonder also if I need my MAP sensor (I think- on the firewall left of the vacuum tree) hooked up to a vacuum line. My car has no egr or a/c if that has anything to do with it. Thanks!
