'78 SC vacuum line Where does it go?

[jhh967]

I'm installing a '78 CIS/ ignition distributor on an '83 SC engine. There is only 1 vacuum line on this distributor but I can't see where it goes. The manual says it tees off of the EGR valve line on California cars, but what does it do for the 49 state cars? The only place I can see is maybe it tees off of the line on the back of the throttle body that goes to the top of the vacuum limiter and the thermo valve??????

Thanks!

Mine is connected to the bottom of the throttle body. A second outlet on the throttle body is capped off.

Hope this helps.

Thanks! On mine there is only one (small) outlet on the forward side of the throttle body and it goes to the vacuum limiter and tees into the bottom connection on the warm up reg. There is a small outlet on the rear of the T.B. also but it goes to the top of the warm up reg. ?????

On the '83 T.B. that I still have there are 2 small outlets on the rear and one on the front (double vac canister).

The P.O. of the CIS said it was a Euro. Are Euro distributors mech only advance?

Thanks!
