I pulled a complete dash from either a 91 or 92 Bird. There was a yellow box tied behind(factory ties). I was just wondering if it's a part for the air bag-if not what is it? Has a part #12077849. It has 1 plug on the end of it and it's yellow. I have a pic but it won't post. Anyone know? Anyone need it?

 

That's the coveted 'buffer box' that convertes the signal to operate the electronic speedometer found in the Firebirds.
Someone who has de-ECM'ed Firebird will need it as they usually throw away that box because they don't realize what it does.

 

Are you sure? I thought this was the buffer box(in pic). If it is I have something different.
Were you able to check the part # I posted?

 

Apparently I was wrong....doesn't the airbag system have yellow sheathing on it's wires or something like that?

 

I have no clue as I've never had any cars w/air bags. I lucked up on this car in the J/Y a few yrs ago. When I pulled the dash out(for my conversion)it was mounted back there.

 

theres a yellow box with a yellow wire attached to it. Mine had a label on it that said it had to do with the airbag.

 

They didn't have the air bags in 86. Check to see if it has a part number on it and call the dealership to find out what it is by the part number. I have seen one of those in an 86 bird in the junkyard but didn't pay much attention to it. This bird had the 145 mph speedo and the electronic dash.

 

it came from a 91/92 bird w/an air bag.
Can I e-mail the pic to you and can you post it for me?

 

might be the cruise control brain

 

Can I e-mail the pic to someone so they can post it for me? I can't get it to work.

 

Hello Tony,

I contacted a buddy of mine that works in the parts department at my local dealership and gave him the part number off that piece. That is no longer a valid part number in their computer and did not show a cross reference for it. All he could tell me, based on the information I gave him, was that it was a part of the airbag system. Which part it was, he couldn't tell me. Sorry.

 

That's cool I appreciate the effort.
Know anyone who'd want it? I have no use for it.
Trickster--ever get the pic I sent you of it?

 

Hey Tony,

I got the picture all right, I used that for the reference when I talked to my buddy this morning. The picture he had in his computer showed three possible items but no definite location for them except for the impact switch on the transmission tunnel under the center console.

 

Can you post the pic here for the guys who don't know what we're talking about?

 

I sure can, here it is. Anybody got any ideas.

 

I have the same issue. I have an 89 formula with a little yellow box in the dash and I have no idea what it is

 

Yhat is the speed sensor buffer for the speedo. Here is mine
Goes for $0 to $90 on Ebay, so you might want to sell yours. Also used in corvettes and cavaliers.

 

Thanks for your help.
