    Hello,

    New to TacomaWorld, new to the Tacoma.

    I recently purchased a 2021 Tacoma SR5 Access Cab 4-cylinder. I wanted to install an OEM bed light kit. I can find all sorts of info on installing the actual lights, but my question is about installing an OEM cargo light switch and relay in the cab. Mine only has a blank in the dash where the cargo light switch is in other models. I only have the third brake light.

    The OEM bed lights description says if you don't have the switch you must install a switch and relay. I'm a fairly handy guy, but don't want to splice in to the electrical system on a brand new vehicle. Is the switch and relay just a plug in installation? It looks like there is an unused wiring harness behind the dash below the cargo light switch blank off. Is this for the cargo switch?



    Will I need another relay to plug in?


    Thanks for the help. Hoping my first foray into upgrading my Tacoma will make for an enjoyable hobby.

    You have the relay already. Since the vehicle doesn't have or fit the Cargo Lamp you could get the mating connector to the cargo lamp switch connector. Unless you need to turn them on/off at other times. By getting the matching/mating connector you can have the Door feature function of the missing switch.

    P.S. do a test first. Place a jumper wire on the connector (wire side, not the switch side) on the blue wire #5 to white with black strip wire #7,

    check that you have power to the connector behind the rear lamps where the bed lamps connect to.
    This connector:

    Pink wire for (+).

    Can one of you fine folk point me to a thread about Cargo light wiring/relay for a 2016 Access cab? I looked behind both tailamps, no relay present as I found in one post. Is the Mattgecko setup the best choice for my older truck? Thanks.

    2016 doesn't have the connectors to the bed lamps anywhere.
    The relay is in the cab.

    Thanks Caribe, jumpering the blue to white black did nothing, of course I have a third stop lamp, no cargo lamp. Is the wiring present at the the existing lamp , or skip using that light and run a lead from the relay to whatever lights I put in?

    So just order part 90980-10800, snap it on to the wiring harness, and leave it all behind the dash? $7 connector sounds better than a $70 switch to start with.

    Yes, but you'll also need 2 male terminals 090/2.3II at both ends to insert into the 90980-10800.

    You could also add a DPDT switch non-Toyota type and duplicate the Cargo Switch entirely.

    Did you verify that you have the relay?

    In your year and version there is no connector to the rear lamps. You'll have to add the missing connectors and wires.

    thanks Caribe, yes the relay is there. Does it also serve some other purpose? Odd that the truck would have the switch harness and relay and it goes too nothing. I hoped there was a taped back plug some where near the third brake lamp that would be an easy to tap source for the Mattgecko lights.

    You would have to take down the roof liner carefully, and inspect the harness going to the 3rd Stop Lamp. It's a tiny connector.

    You could always get someone to 3D print or machine you an adaptor or a body guy to cut and shape to location...:D

    Did you find the "extra" connector up there?

    Thanks for the help. I ended up just buying the cargo switch. Plug and play with the cargo switch and cargo lights, no issues.

    Pre 2020, Tacos weren't prewired for bed lights. Install was a bit more involved. Instructions attached. There may be different part numbers depending on bed and cab because of wiring length so double check that. The high mount stop is different between ACS and DCs. A few dollars at Harbor Freight for stick on LED lights would be much easier if you have a bed cover/shell to keep them out of the elements.

    I have spent today on a mission to get the anzo lights I got from a member here working. Added the missing relay, used a switch from a salvage Tundra. Here is what I found on my 2016 access cab. There is no female connector at 14 in 1e1. The relay does power the male pin in the socket as required. Thus no green wire going to the stop lamp. So I will procure a terminal from the same Tundra that donated the switch and run the lights under the cab, through the rubber plug in floor pan under seat and into the sill plate harness space on left side.
