Description

Tombit’s 3rd-Gen Toyota Tacoma Mic Adapter is a complete plug-and-play solution for 3rd-Gen 2016-2019 Toyota Tacoma owners looking to install aftermarket head units into their trucks while also retaining use of the overhead OEM factory microphone. This adapter does NOT require cutting into/modifying any factory wiring harnesses. There’s no need to remove the overhead console assembly or fish wires as the adapter is installed inline with the head unit. You simply plug the harness in, attach the ground lug to your truck’s frame directly behind the stereo, plug the ATC/ATO tap-a-fuse adapter directly into the new aftermarket stereo and plug the mono mic cable into the aftermarket stereo’s mic input and you’re done. If you ever need to re-install the factory OEM head unit, the adapter installation is completely reversible and leaves no trace.

This adapter is confirmed to work with 2016-2019 Toyota Tacoma Trucks. The adapter is NOT compatible with the 2020 and later model years as Toyota redesigned the OEM head unit and wiring harness for those model years. A version of the adapter that will support the 2020 and later model trucks is currently under development.

!!! IMPORTANT !!!

This version of the adapter is specifically designed for use with an aftermarket head unit that utilizes an ATC/ATO fuse socket. Before purchasing, please confirm both of the following criteria are true (if you have questions, feel free to reach out to us and we’ll do our best to assist!)

  • The aftermarket head unit has an ATC/ATO fuse socket. Click here for help in determining what type of fuse your aftermarket head unit uses.
  • The aftermarket head unit has enough clearance around the head unit’s ATC/ATO fuse socket to fit the power connection adapter of the 3rd-gen Toyota Tacoma Mic Adapter

This adapter’s microphone jack and included 3.5mm mic cable (the orange cable) are wired (click here for a diagram) with the tip connected to mic + (signal) and the sleeve connected to mic – (ground.) This is the standard convention for 3.5mm mic cable wiring and what most aftermarket head unit manufacturers adhere to for their mic jacks. There have been some customers with Dasaita aftermarket head units who have discovered their head unit mic jack’s wiring has been reversed, subsequently causing issues with noise/distortion.

If your aftermarket head unit does not meet the above criteria, don’t despair as we’ve got some other adapters coming that should be of help! We do NOT recommend modifying the power connection of the adapter in any way to work with aftermarket head units that utilize a fuse socket type other than ATC/ATO or modifying the power connection of the adapter to pull power from a power source other than the aftermarket head unit.

Please note, if the item shows as “Out of Stock” there are more on the way as these are made in small batches. Please check back frequently to check availability.

FAQ

Below is a list of commonly asked questions we get related to the 3rd-Gen Tacoma Mic Adapter…

Q: Will this adapter work with my <insert vehicle year/make/model>?
A: Probably not. Automobile manufacturers use a myriad of different head units, overhead microphones and wiring harnesses, even across vehicle generations (e.g. This adapter does NOT work in 1st/2nd-Gen Tacomas because the OEM head unit, microphone and wiring harnesses are different.)

Q: Will this adapter work with my 1st/2nd-Gen Tacoma?
A: No. The 1st/2nd-Gen Tacomas use different OEM head units, overhead microphones and wiring harnesses.

Q: Given the answer to the previous 2 questions, will you develop an OEM microphone adapter for <insert vehicle year/make/model>?
A: Maybe. The 3rd-Gen Tacoma OEM microphone adapter was developed out of our own necessity (the owner of Tombit owns a 3rd-Gen Tacoma and needed a solution to use the OEM mic with his aftermarket head unit.) We get this question quite often and my response is this – “We’re certainly open to the idea of developing adapters for other years/makes/models of vehicles; however, there needs to be a significant demand because there’s a fair bit of R&D, testing and production costs associated with these adapters so the ROI has to be there.

Q: What’s up with the 2-amp fuse? Does this adapter pull that much current?
A: If there was ever a malfunction within the adapter, the internal circuity would be destroyed (by design) before the 2-amp fuse would blow. So why is the fuse there? The fuse is there out of an abundance of caution. Once installed, this adapter will be sitting behind the head unit in the dash, likely never to be seen again for the remainder of the vehicle’s life (or at least until someone decides to replace the head unit again.) In the event the adapter’s 12VDC power supply line were to be crimped/damaged during head unit installation or the power supply line were to separate from the adapter, the only thing standing between a complete short to chassis ground is that fuse. So yes, the 2A fuse is there for a good reason.

Q: What’s the current draw/power consumption of the adapter?
A: The current draw of the adapter is negligible at ~13mA with total power consumption at ~150mW

Q: Is this adapter made in the US?
A:
Kind of. Here’s the truth of it – Many of the parts that make up the adapter are not manufactured in the states and if they were, they’d be so expensive that it would result in the adapter costing 3x to 4x what it does now (possibly even more.) With that said, we make a concerted effort to source components from US vendors whenever possible (albeit, many of these components are still imported but that’s the world we live in.) The adapter PCB is manufactured by whichever board house (domestic or overseas) has bandwidth, the required components and a fair price. At the end of the day though, the adapters have been designed and are assembled and tested in Lancaster County, Pennsylvania. Although I utilize an SMT assembly process with my various board warehouses, I personally hand-solder all of the through-hole components, inspect each PCB, assemble each adapter and test each and every adapter.

Installation Instructions

Installation is straightforward as the harness was designed to be plug-and-play; however, if you’re uncomfortable/unfamiliar with working with automotive electrical systems please don’t hesitate to seek the help of a automobile audio installation professional. If you run into issues during the installation process, please feel free to reach out to us via our Contact Us form and we’ll do our best to assist!

 
Important notes regarding adapter installation

  • In an effort to ensure both your safety and to prevent damage to your vehicle, please be sure to disconnect the negative cable from the vehicle’s battery before beginning adapter installation.
  •  

  • While it’s unlikely it would ever need to be replaced, do NOT under any circumstances replace the 2A fuse that’s already installed in the adapter with anything other than a 2A ATC type fuse. Do NOT swap the position of the 2A fuse that’s already installed into the adapter into the empty position!
  •  

  • When installing the fuse that was supplied with your aftermarket head unit, please be sure to use the ATC type fuse supplied by the head unit manufacturer. If you need to replace or supply your own fuse for your head unit, be sure to use a fuse that matches the amperage of the fuse specified by the head unit manufacturer.
  •  

  • When you’re connecting the adapter’s male/female harness connectors to the vehicle and head unit harnesses be sure to use extreme caution so as not to bend the pins of the connectors. The pins of each end of the 28-pin harness are inspected as part of our QA process, but the pins can be bent/damaged during installation if things aren’t aligned correctly. We had an occurrence where steering wheel controls were no longer functioning after adapter installation. It was discovered that one of the pins in the adapter harness connector had bent. Unbending the pin and reconnecting the harness corrected the issue so all of that to say, just use caution when connecting the 28-pin connectors. If you feel an excess amount of resistance when trying to seat the connectors it’s best to stop, examine the pins in the connector and try again.
  •  

  • We advise against modifying the adapter to draw power from other power sources within the vehicle.

 

Disclaimer
Automobile manufacturers do not look fondly on aftermarket accessories that interface with OEM wiring harnesses/vehicle electronics. While there’s little risk of damage to your vehicle by installing/using this adapter, it’s likely the manufacturer of your vehicle would consider the use of this adapter a reason for voiding any warranty claims associated with the head unit and/or vehicle head unit wiring harnesses. By installing this adapter, you assume all risks associated with its use.

 

Installation Instructions
(It’s assumed you’ve already removed your factory head unit in preparation for installing an aftermarket head unit)

 
Step 1 – Ground Lug Connection
Using a ratchet with a 10mm socket, remove the bolt encircled in the image below. Place the bolt through the ground lug attached to the Tombit Tacoma mic adapter and using your fingers, screw the bolt back into the hole. Hand-tighten at first and then using your ratchet and 10mm socket, snug the bolt (do not overtighten!)

 
Step 2 – Power Connection
The Tombit Tacoma mic adapter ships with a 2-amp ATP fuse (black/dark gray color.) The other slot in the power connection adapter is empty. Take the fuse that is supplied with your aftermarket head unit and place it into the empty slot. Take the Tombit Tacoma mic adapter power connection (encircled in red in the image below) and insert it into the fuse slot on your aftermarket head unit (see the image below.)

Do NOT swap the position of the 2 amp fuse located in the Tombit mic adapter’s add-a-fuse tap with the fuse you removed from the vehicle’s fuse box within the Tombit mic adapter! It’s important the 2 amp fuse included with the Tombit mic adapter remain in the top slot of the Tombit mic adapter’s add-a-fuse tap.

 
Step 3 – Vehicle & Head Unit Harness Connection
Connect the 28-pin male/female Tombit Tacoma mic adapter harness connectors to the vehicle connector and the head unit connector (encircled in the image below.) Be cautious not to bend the pins of the connectors!

 
Step 4 – Microphone Connection
Insert the 1/8″ (3.5mm) microphone cable from the Tombit Tacoma mic adapter into the microphone port of your aftermarket head unit (encircled in the image below.)
