A lot of broken parts does not make you a racer; it makes you a slow learner.

I have  that diagram.
I have deleted  egr, and fuel vapor canister.
my issue is two small hard lines  from under the heater / fan  housing.

and what line  goes to heater water temp control? ( from where)

should any ck valves be  in line to  interior, either  boost gauge or  heater controls?


also , not using waste gate solenoid,  using RJC valve,

Thanks

The longer line runs across the firewall to the outlet on the firewall mounted check valve that shows hvac on the diagram.  The shorter line goes to the heater valve

mine are broken off  by the a/c box,   so.. what I under stand is.
one is a feed line, and the other  is only under vac when the heat control is  turned on.

don't have a fire wall mounted  ck valve

( the  three way one?)

You can find them in the Help section at parts stores..think I bought one on amazon.

You need that to keep boost out of the hvac system as well as keeping vacuum stored in the vacuum reservoir ball under the fender.  No big deal on the two plastic lines...connec t them up and if the hvac does not respond, you have them backwards.  I will try to look tomorrow and see if there is a way to tell them apart...I was thinking they emerged side by side.

vac lines.... they do  come out side by side,

ck  valve, I have that  one, and wondered where it went.
also have a single in/out  ck valve,   both on the bench, LOL


it the "map" sensor  vac line  just a direct connection? (intake to  map  sensor)

thanks for your  help,  been  messing with these  things for along time, but   never got into
 making  heat/air things right, LOL

yep, direct connection.

That link that I posted shows where the check valves go.

It's always fun to try to put stuff back together after it's been apart for a year, or more.  :D  that's a sure way to come up with extra parts

and brittle,  broke when touching them,   all original,
I bought the car from my neighbor, who bought it new,
and that was about 20+ yrs ago,

my we4  finally  used more oil than  it leaked, so it was time for  new motor,
problem was, took it apart, and  can't remember  where stuff goes,
its together and running  (after 6 mos)  but still have some small issues,
have brand new ac comp, dryer,  recrimped  the old ac lines at factory crimp , as
 they  were so loose , they had to leak,
went with 206  roller, (wow are TA hyd  rollers noisy!)
big intake valves,  etc,etc, 
found a 911 converter (new in the box) stashed away in the garage,
so in it went,
haven't driven  it yet ,as still hooking up scanmaster, exh temp gauge,
and all the gauges I installed years ago , and  never got working,LOL
T60, alky, 009's,  walbro, hot wire, moser axles, UMI lowers,  and the list goes on............ ..

so where are you now, Robert? what are you doing,  I see Len frequently,
and chat  on facebook  all the time with him,
