this is gonna go on for a while.
Started on the interior today. Again mice here and there. They nearly ate or made next out of all the matting on the back of the rear firewall cover. It may be what I found in the passenger quarter panel.

The advice I was given to power wash the mats was dead on. I am going to try it on the divider too.
- Are the push in fasteners used in the car common? Are there any that are not? The ones on the rear quarter cover and the cover panel under the window are new to me.

- what is the device in the passenger quarter section? It does not appear to be wired to the speakers.

I am not going to disconnect any electrical devices before I put power back on the car to see what works and whats dead.
- the car has both a windshield antenna and a rear quarter antenna. Is this normal? Is a replacement power antenna available? I am assuming a universal power antenna wont fit here.

- Is there a trick to separating the rear quarter window cover from the piece that runs along the top of the windshield? Does that piece need to come off first and if so how? just pull? Ditto for the sill covers? I have been lucky so far and havent broken an interior piece though I have broken some fasteners.

I am beginning to believe the brown sticky stuff is degrading mouse piss. I have found little surface rust and no cancer. Mounting brackets for anything all seem to have surface rust, or corrosion, somewhere. I have yet to stumble across the showstopper repair.

Thanks

The push-on fasteners / clips are common to many Toyotas of the era. There are quite a large variety of types, though. Vary by length and diameter some. Some rounded like the one you have pictured, some with longer, more pointed tip to help make alignment to their target holes easier.

The electronics box in the base of the B-pillar I thought was the OEM sub-woofer amp.

And yes, two antennas are normal - FM "diversity" antenna embedded in windshield + the standard mast antenna in the trunk RH side. Usually the motor is fine and only the telescoping mast with is toothed plastic retractor cable needs to be replaced. OEM replacements were still available a couple years ago, but they're pricy at around $70.

For the antenna, I fixed my mast by using a replacement from

Toyota MR2 Years

Good service and quick shipping.

For the clips, if you search toyota trim clip, you should find them. They aren't too expensive and you will break some.

My experience is you will want to replace the sound absorber - the jute. I am currently waiting on a fancy version crom Resonix that is supposed to be better than jute. I would probably go with thinsulate sound absorber if I could cancel the order.

My car had two antenna cords going into the stock radio.

The finned device is an amplifier. Your car probably had the premium power. If it is 1993, it has two subwoofers - one on each side. Each subwoofer has an amplifier.

Thanks for the responses.
I pulled the antenna out. What a mess. The mast was bowed. The plastic rack was wrapped around its drive drum. The motor armature was locked solid in hardened grease. With the armature free it runs. I cant get its brushes to back off so I cant pop it out. I have to relube it.
I believe a new mast and rack is available both oem and aftermarket.
I want to get it operating and bench tested including the reversing control setup before I store it away. I have spent a little time in the electrical manual and I am not yet up to speed on what's going on with that relay system. It seems unnecessarily complicated but I have to figure it out.
It is subwoofer amp. The harness routing fooled me.
Is there a go-to for a clean replacement radio? Do you leave it in place and hide another one?
I am delighted the car doesnt have the security system.
I have used Dynamat before and will likely use it on the MR also.

Steve,

Please have a look at this thread:

Dr. Bob's Stereo Install - '94 premium audio...

This actually started as a little project to try to get rid of the sickly sweet tropical smell in the trunk. I tore all the interior carpet etc out of the trunk and cleaned using enzymatic cleaners and it is better but not perfect. So, while you are in there . . . I thought it would be better...

I have just been through a lot of what it sounds like you are doing. I wired my stereo to the existing sound system. For the premium sound, there is a main amp that runs the two door speakers and the small speakers in the rear quarter panel. The main amp also feeds the subwoofer amps. I was worried that my amps would be shot, but, they are working fine. If they didn't work fine, I would have just skipped the factory harness and run new speaker wires and used whatever power my replacement radio provided.
