Cruise Control Regulator vacuum line?
I have a 1990 Rx-7 non turbo convertible. I bought the car as a shell and Im finishing up installing the UIM and TB with all vac lines and fuel hoses. I have just 2 areas left (UIM right up against the firewall and 4 way vacuum spider with one open vac plug right up against the firewall too near the one on the UIM) where vacuum lines can go and I only have 1 vacuum line left running from the cruise control regulator to a 3 way vacuum spider with 2 open lines to attach to something but I dont know where they go, can someone please let me know where it goes?!? I have searched the forum, google, followed the vacuum routing page in my Haynes manual, and looked through the FSM and still couldnt find it! I am so close to being done I just want to hook the last of my lines up and start putting the radiator, alternator and intake in. Any help is appreciated, thanks

There is a empty vac line that is capped off on the UIM that I can run it too but then there is still an open vac line on the other end and there would still be two open areas where theres supposed to be vac lines but there would be none to hook up. It might be confusing as to what Im talking about since I dont have any pictures, you think pictures will help?

Here is a picture of the 2 open vac nipples. They are both up against the firewall on the UIM/TB. Anyone know what vac lines go to these?

This is the vac lines that go from the cruise control regulator and I think (but am not sure) that these go to the 2 open vac nipples in the pic above. Can anyone confirm or deny this and tell me where it goes if not to them?

The vacuum spider in the picture above runs to the water thermo valve, double throttle dia., and to that nipple on the UIM in the pic but what does the only open nipple on the spider go to? I keep looking and am having NO LUCK. Same with the cruise control regulator vac line spider with the 2 open vac lines w/ check valve.

Ok so I found out where the cruise control regulator vacuum hose went. It went to the 4 way vacuum spider I thought it went to. I still didnt find out what/where the open vacuum nipple on the Upper Intake Manifold goes. Im starting to think it was used somehow for an automatic transmission vacuum or something. I took the engine from an auto and put it in a 5 speed. Thats the only other thing I can think of so Im going to cap it off and move on. Thanks for the help! ha. . .
