Step by step pictures: Redarc Tow-Pro installation in 2021 LX570 (1 Viewer)

[stonekutters]

When looking for pictures on the forum there were very few pictures of the Redarc tow-pro installation process on 2016+ LX570. There were a few steps that aren't present in the Landcruiser, at least based on the posts, hope this helps!

Step 1: Remove the two screws at the bottom of the driver side panel.

Left side screw:

Right side screw:

Lower panel removed:

Step 2: Remove two 10mm bolts on the left and right side of the main lower panel. This panel surrounds the knee airbag.

Right bolt

Left bolt is behind this plastic trim piece which opens downards

Trim flap open showing the bolt

Step to skip: There is a small rectangular trim piece below the left hand buttons and above the coin holder, there is no need to take this out and recommend skipping this step.

Step 3: Use a trim removal tool to remove the main lower trim piece, its snapped in place across the left, middle, and right

Lower trim left of the steering wheel

Right side trim piece removed (where the tailgate button resides)

Step 4: remove the gas and hood open levers from the trim piece, it slides and moves down and easily comes out

Step 5: remove the empty switch and install mounting panel for Toyota (part 331-TPSI-002)

Back of the switch panel

New trailer brake switch from the front

Step 6: Locate the trailer brake controller connector, mine was on the left most side, wrapped in brown tape, and connected to a dummy connector

Up close view of the brake controller and connected to the dummy connector (note with a flash light it looks orange, without flashlight the tape is brown)

Zoomed out view with the dummy connector with tape on it.

Dummy connector removed

Attaching trailer brake controller: I used double sided 3M tape to attach to the silver box behind the OBD connector.

Connecting cable (I soldered the two wires, added shrink wrap, added electrical tape over the shrink wrap, and then put all of it in a wire loom)

Thanks for sharing the detailed walkthrough and photos of this. Your timing in posting this is great too.

I am planning on adding the Tow-Pro at some point in the upcoming week on my 2017, and this helps a lot.

I’d add step 0: disconnect ground and wait 15 minutes. You don’t want airbags going off.

Oh wow, I had no idea! Thanks for adding!

My “upcoming week” turned into more like two months…

So, a quick follow up since I did the install today.

The photo walkthrough (and reminder to disconnect the ground) were very helpful and reassuring during the install. So thank you once again @stonekutters (and @CharlieS ).

If you dont want to solder wires together you can get the RedArc plug-and-play harness (RED49FR) to go with the LC/LX..

Just beware, you end up with quite an amount of extra wire to coil up and get out of the way.

Thank you! I've got mine siting on the shelf waiting for some free time to install this summer.
