do they have vacuum ports on them ? (should be 2 tubes each)
If so then I believe one is the Thermaval Vacuum Switch (TVS) for the EFE (early fuel evaporation) vacuum valve on the right exhaust manifold, and the other is the TVS for the canister purge valve (charcoal cannister) usually located behind the left headlights on V-8 engine cars.
That is what they are on my 1982 Z
