wire harnes after weber swap??

the leftover wire harnes after instaling the weber ware it hooks to the egr valve below the carb and a green conector sencor thing on side of the manafold can i remove all that also?

Yes, all sensor wiring and egr stuff can be eliminated.
Just don't get rid of the temp sensor wiring.

I'd keep the little vacuum/electric controls you take off the passenger side firewall, even the old carb/air cleaner/tubes, etc. Over the last 6 years I've sold most of what I pulled when I installed my Weber in 2005.

Sooner or later, someone always wants something. Like someone needed the idle-up stuff for his added aftermarket AC, someone else wanted the rubber hose from air cleaner to the front, someone bought the air cleaner assembly with its new filter, etc.

everything has ben removed but that green sencor conector on the manafold and the egr thing by the nipple on the gold housing wats that oxygen sencor for?

Leave the oxygen sensor in place; for you: it seals the exhaust system !!! The wire will do nothing for you.

ok i left it in the exhaust and cut the wire but what about the little green hook up that screws into the manafold? i un hooked it and its not a timp sencor but i un scrued it and anti freeze came out so what is it is it importnant?

That's a coolant temperature sender, but not the one to the gauge (that one is under the thermostat housing); like the O2 sensor, you only need that as a plug now.
