What do these go to?

[batmanfc]

I got my harness loose today. Come across some wiring that I'm not sure what it goes too.

Not sure about these first of all. They sitting near the oil filter but weren't hooked to anything.


These were hanging near where the air bypass would have been if I had one. Not connected to anything either.


This one was also hanging down near the air bypass valve. Not connected. And there is a wire there that is cut. Not sure where it should go but the O2 sensor had been cut. I was thinking maybe it was supposed to go to it?

I strongly believe in that last pic the green connector is for the thermosensor. In the first pic I believe most of that is emissions related with check valves that are connected via vac hoses. Check the FSM or a hanyes manual. Could you give is the year and model of your rx7. that would help us out a alot.

1st pic, the 4 colored ones that look the same are for emissions solenoids. The different shaped green one it the TPS test connector (I think)

2nd pic, black and white ones are to the ACV and I think that longer one goes to either the thermosensor or the BAV.

Most are emissions.
The lighter green one on the left is a check connector and not normally connected to anything.

ACV cluster...
Is the wires away from you pictured below?

That's for the BAC valve or the idle control valve.
The other cut wire is for the O2 sensor, like you guessed.

Ok. Thanks. My car is an '88 TII by the way. Sorry I meant to mention that. Would I need to run the 4 emissions plugs? I'm pretty sure the emissions has been taken off. It has no air pump.

Yea the ones pictured in pic 2 away from me is the ones in the last picture. The ones in pic 3 are relatively close to the ones in pic 2.

Where would the ACV cluster plug to?

I thought the one cut in pic 3 was to the o2 sensor but I wasn't positive. If I were to splice in a connecter from and s5 n/a for the o2 sensor would it work? And I don't believe I have the BAC valve. There are some blockoff plates on the right side of the intake manifold. One is relatively large. It had an aftermarket BOV on it. Would that make a difference as to remove the BAC? I'll try to get some pics today. If I can't today I will definetly have some tomorrow.

The emissions solenoids are not absolutely necessary to allow the engine to run.
3 of them are emissions, while the (darker) green plug is for the twin scroll solenoid for the turbo.

The ACV is normally located right above the turbo, mounted on the lower intake manifold.
I think yours is deleted and blocked off.

Yes, but it's not necessary to steal that connector.
Any 1/4" (female?) spade connector can be crimped on.
Also, BE CAREFUL to remove the outer wire braid shield on the wire itself before crimping the connector on.
The outer braid is grounded on the other end.
If you get this braid connected to the inner signal wire of the O2 sensor wire, you can blow electronics inside the stock ECU.

And I don't believe I have the BAC valve. There are some blockoff plates on the right side of the intake manifold. One is relatively large. It had an aftermarket BOV on it.

I don't know why people get rid of the stock BAC valve.
The BAC valve does a very good job allowing the engine to idle, especially on the street.
Removing the BAC valve can cause idling headaches down the road.

Hard to figure out what you're describing.
Get some pics, and we can definitely help you figure out what it is...

Ok. I will definetly get the connecter off of the other car for the o2 sensor. I didn't know if the n/a connecter would work for the TII. I will get some pics today too. I didn't have a chance to get them yesterday. Where exactly would the twin scroll soleniod hook up? Is it on the turbo which is probably a dumb question? I am assuming it is. Thanks guys will get some more pics today.

The twin scroll solenoid would be located right around the oil fill pipe.
All of the emissions solenoid would be located there.
I have a feeling someone already yanked them all.

The twin scroll solenoid would be connected to the twin scroll actuator located on the turbo exhaust manifold.
The twin scroll actuator is that huge, metal, soda-can sized thing that has a metal rod that extends to the turbo exhaust manifold - if it's still intact.

the flapper that directs for the twin scroll is actually powered via air pressure nothing electrical.

[batmanfc]

Where would the soleniod go then? Sorry i'm kinda confused.

[Rotary#10]

it would be a good idea to take pics and plenty of them. For future notes and bragging right. So you can see where are the connections go. hehe

[batmanfc]

You were right. It has all been yanked haha. Also where is the connector or what does the connecter look like for the oil pressure gauge.
