Curious if anyone knows what these 3 boxes are? This picture is of my dash, right below where the stock stereo would be. These boxes are hidden by the pocket thing that is below the stereo location. I'm wondering what they are and if they can be removed. This is almost a 20 yr old vehicle and lots of stuff doesn't work, if these are related to that, they will be removed.
I do not have any stock stereo components anymore, so if that grey box is the old amp, I'll yank it. I'd like to put my CB and Ham radio here if I can get rid of these. Any help would be appreciated.

 

One is the daytime running lights module.

Can't remember the others, friend has my fsm. One might be a factory amp...

 

My last body (did a body swap over the winter) had the factory amp, I remember it being metal, that's why I'm wondering. That grey box is plastic. OK, the DRL module stands to reason, can't remove that now can I?! Hmmm, that is some prime real estate there for radios. If the lower black box is the DRL, then it's ok where it is, I can work around that. Hopefully someone has the answers.

 

None of those are amps.

Have you ever seen an Amplifier made of plastic? Me either.

The large gray box will say on it what it is, and the small box with the yellow on it is for your rear ABS. Its a Yaw rate sensor.

Not sure what the other one is, but you can call Toyota with the part number and they will tell you.

 

Yes. Factory GM amplifier (made by Bose) in the 1st gen Chev Lumina's Z34. I fixed a few of them, customers had a bad habit of blowing the line drivers out of them.

Excellent, the ABS doesn't work, so it can go! LoL

Well damn, never thought of doing that!

 

You can also go to TRDparts4u.com and click on their replacement parts section, then input the info yourself and it will tell you what the relay is for usually.

As for the amp thing, I have never seen a TOYOTA with a plastic amp
