Weird Vacumm Switch on Driver Side

There is a switch mounted to the valve cover on the driver's side with 2 vacuum lines and one electrical connector. I see no reference to this on the electrical diagram. What is this for?

 

It operates your Flux Capacitor.


(I said it first!! )


(sorry, bro. Somebody with some smarts will be along to answer your q.)

 

This one you are talking about???

 

Yep! That is the beast. So what is it for.At some point, I am going to put in a Duraspark and anything else in the engine bay that is non-essential goes into a box in the garage.

 

Your flux capacitor.



I said it first twice in the same thread.

 

Okay Rick, what does it operate and is it emissions related?

 

It operates your Flux Capacitor.


HA! I said it first THREE times in one thread!! Matches my record set back in '02.


As far as what it does, I have no idea. Sorry.

I was hoping someone on here would've have answered your q by now.


C'mon guys-in-the-know. Where are you? Don't make me bring out the Flux Capacitor card again.

 

Pretty sure that's the flux ca.... never mind.

Here is a quote from Acornridgeman that describes the function of that part:

I have also heard it was used to drive the "Lo Fuel Econ" light in the instrument cluster on later cars.

 

I'm gutting under the hood too. Less is better.
Good thread for reference because vacuum lines are teh suck.

 

If you don't have A/C, the only vacuum lines you need is the one to the trans and the one to the distributor.

 

My Sprint had that sensor in the passenger door pillar and it was a manual. There was no unexplained modules in the car. Never thought to trace the wires to see where it went.

 

And if you have a manual valve body & mech advance distributor, you don't even need those two.

 

I have 3 vacuum ports coming off of a vacuum module mounted to the top of the water inlet. There are 2 vacuum lines going into the distributor advance mechanism. There are 2 vacuum lines on the Flux Capacitor(Rick Book).The exhauist manifold line tees into one of the water inlet lines and goes to the advance mechanism(rear). There is one line coming from the base of the carb which feeds into the Flux Capacitor(Rick Book), then out to the water inlet port and then back to the top of the advance mechanism. I am going to ditch the top line to the advance and see what goes when disconnected.Someone at Ford must have had a vacuum fetish when they designed this!

Hang in there. i'm leaving the country in 2 days.

 

I was wondering what that was, i found one in my trunk...my car has the "low-fuel econ" light but i have yet to find out were its connected. But when i haven low vac it turns on(so its working) i'm thinking its connected to the vac line that goes from the tranny into the frewall then back out to the intake manifold.
