    What are these?
    For sale are breakout harnesses that allow you to tap factory switches in order to illuminate aftermarket switches without the need to splice into your factory wiring. This keeps your factory wiring nice and tidy and is fully reversible. This also allows you to control the dimming of your aftermarket switches with the factory dimmer.

    Products for Sale
    When ordering, just determine where in your truck you want to place your new switches and then select the proper harness from the list below. Choosing the correct harness is essential as each one is made for a specific factory switch you will be "borrowing" illumination from. Your choices are:

    Below Head Unit (ECT PWR/AUTO Switch -- Automatic Trans only) - $20
    Status: Restock week of May 10
    If you drive an automatic transmission truck and want to illuminate switches below the head unit, you will want to order a harness for the ECT PWR / AUTO connector. This harness can also be used to illuminate switches on the lefthand side of the dash as it is the same as the AUTO high-beam switch (2018+ only).

    Left Side of Steering Wheel (Cargo Light Switch) - $25
    Status: Restock week of May 17
    To illuminate aftermarket switches to the left of your steering wheel, you will want to order a harness for the cargo light. All 3rd Generation Tacomas have a connector for the cargo light switch regardless if they have factory bed lights.

    Overhead (R44 Overhead Console Connector) - $30
    Status: In stock
    To illuminate aftermarket switches above your head (overhead console), you will want to order a harness for the R44 connector. All 3rd Generation Tacomas have this connector. It powers all of the components in the overhead console. It is not visible unless you remove the overhead console

    Ordering and Shipping

    Payment is handled through PayPal. If you are interested in a harness just send me a private message or post in this thread. I will contact you with payment details. When your harness is shipped you will receive a tracking number over private message. If a harness is not in stock, the typical wait time is 5-7 business days.

    Shipping is $5 in the USA (AK and HI included) per order. International and US territory shipping available at cost.

    What Happened to the Harnesses w/ Extra Switch Connectors?
    These will be available through retailers later in the year. For now I have stopped producing them and am instead offering a "stripped down" harness at a lower cost than what MSRP will be on those harnesses. The harnesses all function the same regardless of which version you purchase.

    Custom Work
    Customizations of the harnesses shown are available subject to extra cost (depending on parts + labor). I have also performed custom work for a lot of forum members. If you have an electrical project you'd like to run by me just send a PM. I have tools to make interior (unsealed) and exterior (sealed/waterproof) harnesses, change surface-mounted (SMD) components, and more.

    Is this hooked up so you able to control the lighted switch with the dimmer function?

    I assume I can tap this on the output side to avoid cutting OEM harness for a relay for Bed Lights. If this is the case, I’ll take the last one!

    We’re looking at the end of next week for components to show and I can take orders around then.

    Does anyone have a preference on the length of the pigtails? I’ve just been making them pretty short (6” or so) as I assume people’s wire runs aren’t going very far.

    6" is perfect for me. I'll likely splice them directly into 4 or 5 JST connectors so I can add up to that number of illuminated switches. Did something similar with my overhead console....no fancy pass through connector like this though!

    I am in for one as well. I have already spliced my wires, but I am going to be wiring up some switches for a friend's truck and the clean look and reversibility is exactly what he is looking for.

    I think that should be more than enough wire. A couple piggyback connectors on the first switch makes it easy to daisy chain the rest of the near by switches. There are a couple different versions available.

    Thanks for that link! These will come in handy when I piggyback the aux/cig port.

    Put me down! To confirm this could be used for rock lights to illuminate when the rear white cargo light turns on right?

    It can be done but I’d be tapping Pin 5 instead of the two tapped here in the offered harness purely for illumination. I can make you one with the tap off Pin 5 but the rest is up to you (@Boswell requested the same thing). Here’s the diagram:

    @kmorgan3 so I'm a dummy when it comes to wiring. My switches have 4 wires. Besides the +/- wires, I have a wire to illuminate part of the switch when activated and another to illuminate the other part of the switch when the lights are turned on. I'm assuming the two pigtails are for the two different illuminations that are in the switch. Is this correct or am I missing something? Will I still have to tap into something else for the switch to light up properly when the lights are on or activated? Thanks

    Can you link your switch for me? I’ve never heard of em being wired like that. Typically the LED that comes on when you press it is tied to the outboard pin and doesn’t require a separate illumination circuit.

    The harness has a tap for illumination (+) and variable (-) (variable ground controls the dimmer).

    That’s what I thought. So the 4 wires coming out of the back of your switches are:
    • illumination
    • Ground
    • Out (to accessory)
    • In (from power source)
    If you were to use one of my harnesses you would connect the (+) from the harness to your illumination wire and the (-) from the harness to your ground wire. Your “out” on the switch would go to a relay or an accessory and your “in” would come from either a keyed or constant 12V source (most likely from the fuse box).
