Tacoma ‘05-’15 6 Switch System

DEVELOPED, DESIGNED, MANUFACTURED and Assembled in the Rocky Mountains of Colorado, known to many as OFFROAD COUNTRY. Trail riding at 10,000 feet at night requires great lighting and a well-engineered switch system. That is where S-TECH was developed and tested. Simple solutions to Off-Road challenges results in reliability, safety and convenience. Our Made in the USA injection molded switch housing and plug and

play wire harness has a pure OEM look and feel second to none. Please take a moment to read the following instructions and procedures. Since you will be drilling and cutting into parts of your vehicle, we highly suggest that you consider using either a service professional or use professional techniques and practices while installing your S-TECH Switch System.

Please be sure to check our website stechswitch.com/installs-new/

Push the black switch harness and red accessory

wire through the boot and into the passenger

compartment. If you are having a tough time take some electrical tape and

wrap to conceal the sharp connector edges. Spray

with lubricant to make it easier to go through

the boot.

Open the S-TECH box and familiarize yourself with all of the parts that you will be using during the

install.02

Start in the Engine bay and lay the S-TECH Module on top of the engine cover so

we can start laying out our lines. Find the 6-Pin Black

Connector that goes into the switch panel

with the red accessory switched power wire.03

Make a small slit about 1/2” wide in the boot going through the fire

wall. Start in the middle to the left of the factory engine harness and

cut away from the harness as to not pierce the factory lines. Then

stick your finger in the slit and feel for the second side of the boot by

the factory harness so you can feel where you wire

pops through inside the passenger compartment.04

05

Disconnect the negative battery terminal before starting.



4

REMEMBER: Be a Pro!Always measure twice and cut once.

Remove any applied tape. Pull a bit of

excess through about a foot and a

half or so will do.06

07

If you haven’t already, it’s time to decide which side you want the unit on. The

bracket provided by S-TECH allows for both passenger

and driver side. In my case I chose the driver side until I

decide the remaining layout of my engine bay.

Grab your bracket and bolts with the fixed washer and

bolt them down about half-way so you can adjust its

position in the next step of the install.

Attach bracket with the flanged bolts

using these holes.

Tighten up the bracket so it matches the slant of the hood for aesthetics. A

ratcheting wrench works wonders here.08



5

Grab the unit and the remaining 2 bolts and

nuts, and attach the unit to the bracket. Now

its time to make your connections. 10

Secure unit to the bracket

using the remaining 2 nuts

& bolts.

Before bolting the Module to the bracket let’s run our

ground and power cables in a nice clean location behind

the factory fuse block alongside the inner fender.

Go ahead and install the ground directly to the

battery or body ground as this in not a high

amp ground.09

BE SURE TO INSTALL THE CORRECT FUSE FOR YOUR ACCESSORY.

Install the fuse with the accessory manufacturers’ recommendation on the amperage of each fuse location. Make sure it matches with the fuse location in S-TECH. Maximum Total Load 600 watts / at 12V, 72 amps. All circuits are capable of 30A each.

Example: A 50" light bar would require a 30A fuse while a few LED rock lights would usually require less than 10A

4Runner: Next pull the side caps off that surround the fan and

temperature control knobs. To remove these just grab the bottom

with one hand and give a gentle squeeze, then put your other hand

up top and grab the back of the trim and pull firmly straight back

towards the center console.

Tacoma: Remove drink holder by prying out and lifting. Remove (4)

Philips screws on the front and rear console pieces.

4Runner: Once those are off, un-screw the two Philips that hold the HVAC Panel on and unplug

the wires and store panel in a safe place, so as to not damage it. Once unbolted, slide a panel popper

between the pocket and HVAC panel and twist the tool to pop the panel off. This does take a little

bit of force and there are four clips, so keep it as square as possible as to not damage anything.

Tacoma: Remove the cover in the bottom of the storage console by lifting one edge revealing (2) 10mm screws in the

bottom of the storage area. Lift the rear of the storage unit up and pull back to remove this section of the center console. You may need to separate the front and rear section by lifting

the front. Remove the shifter knob for manual transmission models. Lift up on the rear of the front section of the console

over the shifter to remove this section. You will now have access to the installation area for the switch assembly.

Optional 60 Amp Breaker- NOTE: The breaker is marked for the

correct connection on that side. Take your positive lead from the

unit and bolt attach it to the AUX side. Then take the lead from the battery and connect it to the BAT side. Once thats done find a place to mount it. I placed it on the side

of the engine with a screw through a pre-existing hole.

Connect the red terminal wire from the unit to the side stamped AUX

Connect this side to the

Run the wire from this connection to the positive terminal on the

Next take your provided template and set it flush

against the bottom of the rear cubby portion. Take your 1/8” Drill bit and drill 2 holes in the spots indicated by the template on the sides.17

S-TECH 6: First, disassemble and remove

the storage area below the head unit. Drill a

3/4” hole in the lower tray on the left side of

tray as that is where the wires are linked together.

Remove any burrs to avoid the risk of a wire

getting cut.15

Position flush against the back

Drill here using the 1/8” bit

Now take your switches and housing and feed

the rear connector through the hole in

the rear. NOTE: before inserting it remember to

remove the stickers on the side of the housing

covering the holes.18

Push connector through the hole you made in the back of

the tray

Remove sticker and slide housing into the tray

16

S-TECH 4: 4Runner only. Not required on Tacoma. Now you

will need to pop the USB plug and power outlet out of the pocket

piece so we can drill our holes for the switch panel. USB is easy and

will push right out. The power outlet needs to come out in two

pieces. First step is to pry the one plastic tab away from the metal

body of the outlet and then slide the metal sleeve out. Once the

metal sleeve is out, compress the 2 plastic ears into the plastic

tube so you can push that out of the panel.

Your housing should sit perfectly flush.

Reinstall console in reverse order.21

Reassemble the lower dash piece with your

power outlet and USB plug and reinstall

into the vehicle. Now reinstall the rest of the

center console and dash back to factory.20

Push the housing all the way in and the

holes should line up perfectly. Screw in the 2 small black screws.

Go ahead and fully reassemble the tray

and shifter area back into the area. You

can easily connect to the switches later by removing the trim

piece on the driver side of the tray.19



10

Be sure to note the direction of the fuse tap relative to the Power Distribution Box. Failure to install the FUSE TAP in the correct direction

will result in NO POWER to the system. Use the supplied Fuse Tap to provide for an “ignition on only” 12V source. CONNECT Fuse Tap

to accessory on only location. This will enable the system when the ignition is turned on. Do not install the red accessory wire directly to a

12 volt source like a live fuse or the vehicles 12V battery as this will drain your battery since the lower LED lights will be on all the time.

Some customers have chose not to use to fuse tap and have installed a secondary switch (see inset photo) to the RED Accessory

wire circuit to turn it On/Off manually without the ignition on. However be very careful not to leave it on too long,

it will drain our battery.24

secondary switch* *Optional secondary switch available on www.stechswitch.com/accessories

Now that we have our wires plumbed

where they need to go, securely fasten them

up out of the foot well and away from any

moving parts.23

Now it is time to connect the red accessory wire to our included fuse tap to a key on circuit. For

4Runner: Pull the fuse cover on the driver’s side kick panel area and

take a look at the cover and find the blank slot indicated in photo.

Tacoma: Remove the “pull-out” panel on the lower dash revealing

the fuse panel. Look for the ACC fuse,

a 7.5 AMP fuse.

Once done connecting your loads tuck the

wires under the box for a nice professional look.

As you add accessories be sure to install the correct fuse for each

accessory.

25

Now before we connect it to the Positive

terminal on the battery, remove the fuses as

you will only need them as you install

your different loads to ensure no accidental

short circuits. Once this is done connect the

main power line to the battery.

Be sure to install the correct fuse for each of

your accessories.

Connect your battery, take a seat and turn on your ignition and

if you did things correctly you’ll

be greeted by the illumination of the

switches!
