Cargo lamp plug pin number for tow mirrors

Hello all! Long time reader, first time poster. I’ve not done much with my 2010 CrewMax SR5 other than swapping some newer wheels and tinting the front windows. I recently bought some new tow mirrors and want to wire the spot lights to my cargo lamp. I was going to just use a fuse tap however I discovered that the fuse for the cargo lamp is always hot so I figured I need to tap into the actual plug. I’ve searched all over this forum and can’t find anything for the 2010 pin location on the plug that I would need to tap into. I’ve been trying to search the file that Rainman posted but I’m struggling trying to decipher those schematics… and struggling would be an understatement. Has anyone ever done this on a 2010 and recall which pin they used?? Or where the plug is even at… driver side or passenger side kick panel?

 

I’m trying to find the cargo light wire to install some towing mirrors and want to tap into that wire for the small spotlights on the side of the mirrors. The schematic for my 2010 Tundra SR5 says there should be a brown wire going from the relay to the back of the cab where the light is. I tried the front driver side and rear driver side under the panel that runs along the door sill. The only brown wire is the one that twists together with the pink wire (neither of which I’m testing with a test light). Anyone know what wire I need in there?? I think I’ve tested everything else under there. The only thing I get power from is a thicker blue wire under the driver side sill, it doesn’t continue to the rear sill. But when I turn the switch off it still stays powered. I’m stumped.

 

That brown wire may be the one you are looking for.
Odd that it is wrapped around the pink wire.


This is from a 2015 bed light install PDF, but the connectors and pin numbers seem similar to your 2010.
It shows where the brown wire originates near the underdash fuse box behind the lower dash.

Part Number: 00016-34021

DC connector
Pin 13 - brown wire.








Good luck..

I don’t know. The brown and pink wire I can see come right out of the yellow airbag plug behind the driver side kick panel. They wind around each other there as soon as they come out of the plug so I assume those are the same winding wires under the door sill. I’ll have to look for that brown wire from the plug pic you posted.

 

If that wire is red and not pink, you might be on to something there..
P4 and N11 sensor wires both run that way.

Good luck..

 

I tied into this circuit on my ‘08, driver’s side kick panel area for sure. I can’t remember the wire colour, but I’ll try to remember to take a picture or two tomorrow.

 

So I remembered, but wasn’t able to get any pictures due to access a lack of access without disassembly, and can’t do that at the moment. The panel under the steering column needs to be removed to get in there.

I was able to peek in there with the end panel popped off the dash and see that it’s a brown wire I tapped into and best I can see it was from pin 13 of the DC connector like the diagrams show.

There’s a convenient ground point behind the side kick panel if you need that too.

 

ugh ok I was looking in the wrong place. I was looking behind the driver side kick panel. I just read 1lowlife’s comments and pics again and realized he said “behind the lower dash” I should have read it more carefully. He spelled it out for me lol. I’ll take a look behind the lower dash once we get another warm spell. I did at least run the wires from the door panel, through the door to cab grommet, and into the cab. So I’ll just have to find that plug and cargo wire and tap in.

 

Ok so I found the brown wire and verified with a test light. The red wire taps I have say they go to 22ga. Apparently that brown wire is even smaller than that because it didn’t even cut through the outer sheath The only taps I see smaller are those Posi-taps. They say 24-26ga on the mini black and red style ones. Do you recall what style wire tap you used? I have all my wires ran, the ground done, and now I’m stuck due to too thin of wire for my taps

 

I clipped the wire, stripped, used a non-insulated butt connector to reconnect with my tap wire in parallel. All with dual wall heat shrink over top.

I absolutely detest tap connectors, even in interior applications. Not fun or easy doing it the way I did in that spot, but worth it to me to have a solid connection.

 

yeah it’s definitely tight quarters in there. I’m afraid to cut that wire in fear that I might not be able to reconnect lol. What’s the benefit of the non insulated butt connector vs the insulated?
