How to connect a trailer brake controller to a (late?) 100 series TLC

don't remember the rating but I think I used some generic little (like 1in across) $5 4 blades black box guy from a generic car parts store, maybe even Radio Shack. Has worked fine ever since.
 
added: On an unrelated note, I would be really careful about towing a big trailer and heavier car with a 100. I'm thinking 5000lbs is likely pushing it. I'm sure some people here have done it, but I'd look carefully at the numbers and at how much liability you're willing to take on.

Could you elaborate a little? I do want to be as safe as possible especially considering that I'm new to towing.

Am I really looking for a 200-series at this level? ~3900lb car + alum trailer at ~1600lbs is my best case scenario...
 
not the best place to discuss that and I may be overly careful and wrong about this anyway. Plenty of threads discussing towing capabilities. Or start a new one for your specific situation. I don't know anything about the 200, really, but would not expect the tow rating to be dramatically different. Look up the specs or ask in the 200 forum.

Fair enough. I did look into this beforehard: 100-series 6500lbs; 200-series 8500lbs; LX570 7000lbs. I'll search a bit more. Thanks!
 
I used this thread as a guide to install a Redarc Tow-Pro V3 into my 2006 LX. I also used a Tekonsha 3040 wiring harness that I cut and spliced into the Redarc provided one. There is a Redarc harness that is specific to Toyota but it was not available at time of purchase. Part number TPH-021.
I decided to remove the knee panel to run and secure the wires as best as possible. It did not take more than 5 minutes to remove the panels.

Parts included:

If your truck has the tow package, you will find the connector here.

I drilled a 1" hole into the locker blank plate and installed the provided switch mount.

You can see the controller box mounted just above the dead pedal. I used the heavy duty Command strips. If they fail I will find a better solution. This location gives me easy access if I need to remove it. The wires were cleaned up with small zip ties after this photo was taken.

Final product. Very clean installation and does not take up a lot of dash space.

So I know this is a 20 year old thread... but it helped me hook up my brake controller today so thank you.

added: later posts suggest that it is possible to just squeeze the black tube and then access the plug, without the need to remove the tube. YMMV.

But then you can't paint the "knee brace" metal.

Thanks for the bump.
I have a 2000 and had to run all the wires and tap into the brake circuit for the Prodigy but it worked out. Just finally got to it two weeks ago.
I followed along here:
 
Appreciate everyone’s contribution to this thread. 2006 UZJ100 with October of 2005 build date and tow package (tranny cooler, factory tow hitch and 7 pin connector). After several hours of standing on my head digging around and above the cross heater vent tube looking for the infamous white connector i had to start pulling pieces of the dash apart.

There was no way to get at the plug without this process on my truck. The plug once I found it was taped into the harness behind the steering column.

I ordered up RED82CR - Redarc Tow-Pro Liberty Brake Controller w/ Custom Harness from eTrailer. Service and shipping was seamless. The harness was a direct connection and the red module is secured to the underside of the vent tube with double sided Gorilla tape.

All of the blanks in the left switch blank are filled on my rig and I did not want to accidentally bump it with my leg or knee so I mounted the remote switch in the center console. It was a PITA to route it all but the efforts were worth it.

Everything works great… except the HVAC auto controls! During disassembly/ reassembly I neglected to pay attention to the small corrugated white tube and the temp sensor. Pull it back apart, clean the sensor now, connect the tube and Viola!
