Throttle Body Replacment

[parv121 3]

Hi

kindly asking for advice please.

i need to replace my throttle body and have brought one from ebay.

my old one had 3 connectionso the bottom, 1, vacum advance hose + 2 for the black hose formed in a V shape.. however the new one from ebay has 4 connections, the vacum, 2 connection in the V shape plus one more to the side on the V shape connection.

my question is what is the 4th connection for and will the new throttle body work on my xu5j engine?

I had this years ago-plumbed it in as old one and used silicone and a self tapper on the "extra" one-cars still running like that!?!-never got round to changing throttle body back after cleaning it

You'll find one of them isn't drilled and does nothing. I've cut it off before now.
