throttle body replacement
 

Hi Guys,

I'm replacing the throttle body on my 1997 Mitsubishi Lancer CK1A, running a 4G13 EFI economy engine.

I already bought a used throttle body from a used part dealer. Everything is exactly the same accept for the vacuum ports on the top of the throttle body. My current throttle body has 3 vacuum lines connected to it (P, E and something else) whereas the replacement I got only has 1 port while the other two are sealed off. Can I still use the replacement and cap of the other two vacuum lines? I believe these lines are from the EGR

Another option I'm contemplating is rebuilding the current TB using the good parts from the replacement.

Your expert advise will be greatly appreciated.
