David,

Will try to help with what my alltrac had with its TDSE, the antenna was in the drivers
side A pillar, the alltrac had two wires going to steering column harness. On the alltrac
these were two green wires that were the last two wires on the outside of the harness.
All of the rest of the wires were in plugs that connected to plugs from fusebox on
drivers side kickpanel

Has anyone figured out if you can have multiple remotes working with the TDSE at once?

I thought I broke my remote so I got more from eBay. Well it turned out the one I had is working again and now I have 4 extras. Do you need one David?

Thanks! Any idea what wires in the column harness are spliced? My 185 has the TDSE...I guess I could just pull the cover off of the column and see for myself.

Kevin - how much do you want? I went looking on eBay and couldn't find anything reasonably priced. I bought a generic remote from a store that's supposed to work and I'll report back on whether or not it does once the TDSE is installed.

Okay. For grins, I plugged in the TDSE harness to the TTDS ECU and horn defeat button. The fob programmed with no problems (thanks Kev!) and it locks the doors.

What I do not have is remote unlocking and the parking lamps do not flash when I set the alarm with the fob. Looking through the electrical manual, the tail light relay has a light green wire and the door unlock switches both have black/yellow wires (but the book shows them going into a 'control unit' so I don't know how they're tied together if at all). Based on that, I'd think it's a fair guess that my two dangling mystery wires are to unlock the doors and flash the lights....but I'm not confident enough to go splicing into the harness yet.

If any of you with TDSE could look at the wire bundle by the driver's foot relay block and see if there are two splices involving a light green and a black/yellow wire, we may just be in business!

The unlock portion of the TDSE is pretty ingenious.

When you unlock the passenger door with a key, or turn the driver's door key a second time, it grounds the signal from the lock ECU. When this signal is grounded, the lock ECU sends another signal to the lock solenoid motors and unlocks both doors. The black/yellow wire from the TDSE splices into the black/yellow wire in the bottom bundle at the driver's kick panel. When you activate the key fob, it grounds the circuit, making the lock ECU think that the door has been opened with a key. When it senses this, it unlocks both doors.

That leaves light green, which has to be lights.

On another note, I read in my research that the two button remotes can be programmed to work with two different cars (one button per car). Fortunately, my ST185 has the Security system upgrade, so I can test that theory out when I get the MR2 back together.

I decided to leave the green wire dead ended. I don't really care if the lights flash when I arm and disarm the alarm.

If you have one of the 2 button remotes, you CAN program it for 2 cars. I have mine so the top button works with the MR2 and the bottom button works with the All Trac. Pretty cool...gives me 2 remotes for the All Trac too.

nbvolks traded me his TDSE for a very rare roof rack bike mount that I had. In my research on how to hook it up, I did find several posts on MKIV Supra sites that referenced that the TDSE module itself was still available as recently as 01/04. It's the plug 'n play installation kit that isn't available anymore.

Yup, the 2-button remotes do work on both cars. The one from my 94NA works both the 94 and a 93T with TDSE.

One thing though ... in the 94s, Toyota's switched "TDSE" to "TVSS". Physical placement of the "horn defeat switch" has been moved to the ECU under the seat. In its place is a glass break sensor. (They switched both of them.) There is nothing else different I can tell without having take it all apart.

I just got the remote that I ordered before Kev offered me his. It's from http://www.keylessride.com and they retail it for $50 shipped. They also sell them on ebay (where I got mine) for $39.49 shipped. I just programmed it and it works fine - so does the one that I programmed yesterday, so you can have more than one remote per car.

It's not a Toyota remote, but it's new and it's smaller than the OEM one. Their part number for it is 5221

Glad everything worked out well for you David. You should definitely wire up the lights though so that it's complete.

I will put in my 2-cents that this should be sticky in the audio/security section. Enough people have issues with TDSE at times.

Agreed and done.

Nathan - the wire that the light green splices to goes into the back of the tail lamp relay and was not easy to get to (from what I could see). That on top of the fact that I didn't like splicing cemented my decision. The car is put back together already, so it shall remain lightless.

For us Canucks, all AC systems were dealer installed options- some USDM car rolled off the factory line with the cool stuff

And no, don't bother trying to get one. Marc Summers bought the last remaining TDSE in North America years ago.

And also to add ...

The 94+ TVSS (not TDSE) does not have the feature where the using the key in the lock will disarm the system. If you open the door or trunk with the key (when system is armed), it will go off. You will need to cycle the ignition to disarm it.

If anyone's still looking at this thread, I've posted a scan of the whole TDSE manual, what little there is of it - just got a unit, & now I've got to figure out how to hook it up.

The TDS doesn't have any adjustments. You can't turn it off - it's completely passive and arms when you lock and unlock the doors with the key out of the ignition. There is no sensitivity because it doesn't have a shock or glass breakage sensor.
