OK. So I found these Wiring harnesses just loose inside my car on the passenger side. They sit just above your feet. Anyone know what these go to? My car is an 88 RX7 NA.

edit: added my car type.

 

does everything work? if so, dont worry about it.

 

the red and green look like the stock amp for the radio on clarion equipt cars, and unused on base model.

 

Well I am having Idleing, power loss issues when you turn the steering wheel. So I am looking at everything right now. Thanks though its good to know something isnt missing

 

Yeah, those things circled have no bearing on engine issues, the large plug circled by red is for something attached to the trim plate the speaker screws to (dunno what the thing is right now.)
green circle is useless.
blue and orange are for the speaker.

 

The ECU signals the BAC valve to add more air when the power steering pump is active. This compensates for the decrease in idle speed. This is where you'd want to start looking. Download the wiring diagrams and have fun.

Honestly though, unless you're stalling in parking lots, just ignore it. Tapping the gas a little does the same thing.

 

Cannot remember (I can go look at mine tonight) but, either the red or the green plug is for the factory alarm ecu. (I have an 86 N/A sport and removed that crap from mine... I will post again tonight an let ya know which one is which. (I labeled mine just in case i wanted to put that crap back in...not sure why, just old habit)

Red circle is for the Theft Unit.

Orange is for the A/C relay that is missing.

Blue......you don't show how many sockets nor the wire colors ....so you figure it out.

When you turn the steering wheel, you make a simple switch at the pwr steering unit. That switch sends a gnd signal to pin 1R on the ECU. The ECU tells the BAC or the Air Supply Valve (Turbo car, I think) to open up and up the idle speed.
