couple of hook up questions

[RangerWill]

ok. Issues finding a couple hook ups and where they go. I have a 77 280z with a recent intake and fuel rail mod. it had a egr intake before .now doesnt.

 

First - right above the two injector style connectors on the front of the themostat houseing unit there is a small outlet that looks like a vacum fitting. I have no idea what this is connected to. help please.

 

 

Secondly - middle lead off of the evap canister. no idea where this goes. if you could just fill me in on where all of them go I would appreciate it. now that my intake no longer has an emissions on it. what do I do with that line?

 

 

 

thanks again guys.

First, that is your temp gauge sending unit, the wire comes from drivers side near the strut where the ground wire is from the intake to the body of the car, by the strut.  Runs alongside the wiring harness on my '77.  PINK in picture

 

Second, the middle of my canister says "PURGE" and the hose goes across or in front of the valve cover to a bung on the intake behind the Cold Start Valve.  Its a vacuum supply for the canister.  GREEN in picture

 

And if your talking about the hose that comes of the ported vacuum switch on the heating plate with the coolant lines, mine used to go to the EGR, I've deleted all that crap off mine but it was connected to the BCDD under the TPS.  I have mine plugged off.  YELLOW in picture.

 

Hope that helps.

awesome. that hels alot. futher question though. can you tell what color wire is coming out of the fire wall for the temp sensor? looks like im going to have to jump back into it. no idea where that wire went. thanks

Mine is a dark brown, almost black wire.  I'd think if you followed the harness coming out of the cabin to the engine bay you'll probably find it.  It's separate from the big glob of injection wires.
