Unknown Connector, 89 2.3

[4cylredfox89]

I wanted to know where this came from or maybe even deteriorated off from my harness. Possibly, even a previous owner cut into wires. Im not a mechanic, but would like to know if this is part of my idle issue. (I know I currently have codes [31,83,84,31]and one time I actually put the EGR vacuum solenoid in backwards because of broken connector and then 83 came and next I put it right so I got 84 next, but I believe 84 came because the computer can now know that it's 84 which is EGR vac solenoid.. right??) As well I had code 23 disappeared after dropping Lucas oil for a while in the gas tank.

Googled it plenty of times to find out maybe it's a speaker connector or iac pigtail, but I also have looked and don't see any connections around like this... Maybe its hidden and you've tackled it before and y'all can be a big help!!!

Green/orange & pink/light blue wire.

Maybe one of these two switches?

Speaker plug is what I would guess it is

RH rear speaker is Pink/LB and Dark Green/Orange wires

It sure looks like a Tab or Tad plug. Just a guess. I suspect you don’t have those with the codes you’ve provided.

TAD/TAB's have trhe clip on the long side

 

[Mcmahst]

I stand corrected.

Ive been suspecting maybe I had the tad and tab solenoids before and previous owner did a delete but I have the 2.3 for about 12 years now and when I learn about the fox 2.3 I don't reckon this 89 lx has any of them or at least to my best knowledge.? As well I didn't seem to find any Xtra wires by the firewall (see pic below);

On my passenger side I have this red/ green for EGR vac solenoid, & unsure what the red/ yellow is ... Maybe to evap test?

Now I want to believe it's that stereo wire, I do have after market speakers, I would've kept original radio and speakers, but it's all kicker stuff so I will see if my speakers retain the original wires or new, mostly likely new I bet. (Will report this later)

...on the other hand. I don't know anything about this one ----> Could it possibly be the WOT A/C CUTOFF.. the reason why I say this, I would be at 30 mph tthen I push the gas down for pickup the next thing happens is my box blendor door by passenger feet opens up and starts spinning and blowing air into the cabin..
I've wondered many times when I noticed this what it could be, I think it happened after I connected my negative battery ground on the battery wall back up because it was never attached In this first place. Can you guys give any Reasons why my battery ground to the wall then to the engine harness wouldn't be connected at battery as well?

So the purpose of this switch is to cut off the ac when @ WOT?..
Say if my ac is off and I'm on freeway then I pass someone and my little door by the passenger feet opens and the little turbine wheel starts spinning, that means it's kicking on some how?? Or vacuum opening the door?

If these two solenoids were removed will I get codes for them being gone

If your A/C is [On] and you mash the gas pedal, it shuts off power to the compressor clutch.

This is a 2.3L car right?

Those cars are wired differently than V8s. No AC WOT relay. That’s all controlled in the cooling fan module under the dash.

I’m 99% sure that’s a speaker plug. I’ve never seen that particular 2-pin connector used anywhere else

Yes. 81 and 82. Do not affect how car runs. You can use resistors to simulate the solenoids and eliminate the codes if you wanted

I think you nailed it.

I think you nailed it.

Thank you guys, learning this car stuff is really tough but easier when I got you guys who know what there talking about! I appreciate you guys foreal. My foster dad is no longer around so stang net is my go to!
