I'm trying to get my MEVI acessories together and was wondering if i would be able to use this solenoid in my MEVI install? If so which is connected to what?
Which goes to the Actuator on the Manifold?
Which goes to the Vac canister?

 

how does the MEVI set up get routed?

evap or egr solenoid?

ugg i really cant remember off the top of my head which of the 3 do what. i have them all figured out but my note are in my garage. i can help you out one way or another. one of the 3 may work..... maybe

 

never seen that one before

 

you should be able to use that solenoid... this is how i had mine hooked up..

black= groud..
yellow.. goes to the rpm switch signal wire..

as far as the inlets on the solenoid..
one would go to the actuator, and the other one to the vacuum canister.

 

that is the one Jay25 sent me. i would like to use it since its an oem part

 

I believe the leg that is all alone on the bottom is the common of the vacuum switch. Try blowing through it, air should come out of one of the remaining legs - mark the leg it comes out of. Now, put 12v on the leads of the vacuum switch (I don't think polarity matters but I'd assume y+ bl- ) and blow through the single leg again, air should no longer pass out of the leg you just marked but should now come out of the other one.

If this is how yours works then do this: hook your vacuum canistor, with check valve, to the single "common" leg of the switch then, hook the VI actuator to the leg that is NOT marked.

Hope that makes sense and good luck.
Btw, I've got a couple of extra Harlan switches that definitely work if you're interested in one.

 

Pm sent, with pic...

 

do i still need to use a relay if i am using this soleniod? also i when i blow in the bottom of it air does not come out. it comes out if i blow in the top one it will come out right under.

 

unpowered air will flow from the bottom to the top. when power is applied air will flow from the middle to the top. i have the same solenoid in front of me.

 

Well unpowered i am getting airflow from middle to top and nothing from bottom. When I power it the same thing? Should i assume this soleniod is done?

Also with this type of soleniod do i need a relay?

 

If you power it up and the pathways don't change between the legs then yes, I'd say the solenoid was bad. Does it make a clicking noise when you power it up? As for the relay, that depends on whatever is activating the solenoid. If you're using a Harlan switch then yes, use a relay. If you're using the Summit or someone elses RPM switch then you'll have to check with them.

 

The summit switch does not require relay.
