front passengers side of an ea81 . where do the vacuum lines go to ?

I'd take a two or three inch piece of vac hose and connect the two nipples to each other. And then I'd just move on. As to where they go,I have no Idea.

There is no need to connect them together - it's a thermo-valve and if it's not hooked to something *else* then there can't be a vacuum signal to it - thus it is an inert item as far as the engine is concerned.

 

There are several thermo-valves used on the EA81's - could be for the EGR, or for one of the mixture signal's to the carb. Most of us don't have one located there so I'm not sure what to tell you. I say take a critical look at which functions you want and which you don't - EGR could use a thermo-valve as it makes cold-running really poor. When I hook up EGR to the Weber's I typically run it through one of the thermo-valves (assuming they are working) as that keeps it from opening when cold....

there should be two nostrils coming out of the front of your car.they are located on the hood, the very front lip.these are attached there, and breath steam whenever it is appropriate.cheers, rbain
