I have a 95 gsr swap that im trying to piece together... im almost done and tonight i put on the wiring harness... theres this big metal bracket/ clip looking thing on the underside of the manifold.. it looks kinda like what you would see on a bicycle for holding a water bottle... and there was a plug that looked like it was going right towards it... what goes there?!! i cant find it in my repair manual of online so any help would be greatly appreciated! thanks guys

 

its like a mini vacuum source box. as far as i know it my gsr ran fine without it.

 

That metal bracket holds the vacuum box for the IAB (secondary butterfly) setup on a stock gsr manifold. The vacuum canister has a connector on it for the plug you are talking about and also has a vacuum hose coming off of it.
