Usually the most daunting task for me is figuring out how to access the wiring. This first section is about how to do that.

1. You will need a fused source of constant +12V. If you do not have this readily available from a previous mod, use a voltmeter to find an unused location on the fuse block. Install a Low Profile (LP) Mini fuse add-a-circuit tap, with a 10 A fuse in the top location, and verify that the +12V is available at the tap’s crimp output wire. This will be used in a later step. (I also use the MESO Extended Fuse Box Cover).
2. Remove the power, disconnect the battery GND terminal.
3. Remove the plastic driver side door scuff (sill) plate. Note where the white tabs are underneath. Here’s some photos and the Toyota instructions.
4. Remove driver cowl side trim (kick) board. First remove the round plastic cover down by the dead pedal. Use a small blade screwdriver in one of the holes to spin the whole thing counter clockwise and off. Pull the panel toward you to release tab at the top. Look behind the panel and see the clip toward the floor. I used as long shafted screwdriver to release the cover from it.
5. Remove the left hand garnish piece under the Fan control knob.
6. Remove the lower instrument panel. There are two bolts and 13 clips. Carefully pull the panel forward from the top to release the individual clips as you work around the edges of the panel. You can remove the ebrake cable if you like, I left it attached and just layed the panel on a towel
