Under the passenger kick pannel, there is the ecu, and some other little box to the left of it.

Any Idea what it is?

My car is an 85 GS.

 

There is no ecu for a 12a.

 

I know what you are referring to, I have the same in mine (obviously as i have an 85) I too, am stumped. I never really thought too much about it till now, and am fascinated to find out.

 

I have my ECU from my '85 sitting here beside me and don't see any other box. Can you take a pic?

 

I can but it won't be for another 5 hours or so. If this thread is still going then I'll take a snap.

 

yes there is,

84-85 its in the chilton's, maybe haynes. look in the emissions system diagrams


****** newbies, j/k lol

 

Yup.. As V8kilr said, 'tis a computer for the emissions system...

Well sorry when I think ecu I think like injection and ignition control. Not an emissions control computer.. :P
And don't ever call me a ****** newbie agian

It's NOT an ECU. It is a CPU. It controls the ignition key light, the timer for the lighted keyhole (driver side), receives a signal from the ignition key and oscillator to relay a signal to the instrument cluster buzzer to sound when low oil/radiator fluid are present. I also think the delay/relay for the wipers is in that unit also.

There are also some other "smaller" relays in the area that control the antenna and some other things I don't remember now.

yeah I know the one on the right is The ECU (emissions) btu still the the one on the left....

My car did have an automatic transmission, mabey a controller for it, like in the second gens?

 

See I told you its not an ecu. Just a computer

 

Prehistoric ECU LOL But yeah theres one for all the emissions bullshit. Hell the 79 had a ECU, more like a relay box tho

 

Yea, its a sad excuse for a computer, but technically it is one.

 

depending on what im doing with the car i will just pull it.

 

Ooops, my bad. I totally mis-read the initial posting.

ECU, an atmospheric pressure sensor, and that other little box you're asking about- I can't remember...

so nobody knows what the little box on the left is?

 

Try looking here: http://www.iluvmyrx7.com/1stgen/manu...ram-online.pdf

Its pretty extensive.

 

yeah I've looked in there quite a few times to find out what it is... but they dont show anything that looks like it....

Someone has to know what the hell the thing is or does, and its not in every car as I've found out, what the hell is it?

 

Cruise Control relay thingy maybe? or isn't the the one behind the driver's seat in the storage bin? Hmmmm...

Well the GS didnt come with cruise control... right?

If it did where would the control for it be?

 

Cruise control computer is gold in color and located under the driver's side storage bin...

yeah, I didn't notice the GS part
